Apple's new SpeechAnalyzer API, benchmarked against Whisper and its predecessor

 https://get-inscribe.com/blog/apple-speech-api-benchmark.html

by get-inscribe

7/13/2026 at 4:55:13 PM

Whisper is the wrong model to benchmark against, or rather, there are better models that are state of the art now like Nemotron and Parakeet both by Nvidia, as well as Mistral's Voxtral and Cohere Transcribe.

However, what's funny is, RIP to a lot of the paid apps that simply wrap Whisper, I'm sure Apple will make a native GUI such as a recorder app for macOS that obviates the need for these wrappers, which everyone seems to be vibe coding these days.

by satvikpendem

7/13/2026 at 5:15:25 PM

Also, this test is English-only, while a strong point of other models is to understand different languages without first having to say which one (so you don't need 3 different keyboard shortcuts if you wanna dictate in 3 languages day-to-day)

by jiehong

7/13/2026 at 6:40:18 PM

Reminds me of the time my neighbours must have wondered if I was having some kind of a breakdown when trying out really basic MacOS voice recognition back in the early 2000s. There was a keyboard shortcut and you could say something like "phone number for firstname lastname" and it would theoretically show you that phone number. Thing is it didn't seem to like a British accent, so I spent a good hour trying out different accents, rotating through various US accents, Australian, South African, Canadian and so on. It seemed to respond best to some kind of a melange of Californian / Australian.

Interesting - I don’t think I’ve ever seen anyone from the UK refer to talking in a “British accent” before since we are normally aware of the wild regional variations.

by thebruce87m

7/13/2026 at 8:33:03 PM

Fair point! I think it's a tic from being English and having lived in Scotland for quite a while so I autocorrect "English" to "British", but I've over-corrected here. (Also perhaps something to do with "British English").

Does anyone have any experience with Mandarin STT? What's a good model for this? The use-case I have is subtitling of Mandarin speech.

by arjie

7/13/2026 at 10:44:38 PM

I use Systran/faster-whisper-medium for real-time subtitling, but you need to get used to the context it's used it and the weirdness it translates into. Parakeet has great mandarin>CN text, but running that + a translation model has been tricky and I never got it fast.

by tapland

7/13/2026 at 11:01:15 PM

Thank you for this too. I am running in an offline scope so I don't need speed just quality. I'm willing to do it overnight as well if required.

by arjie

7/14/2026 at 10:55:02 AM

I run it offline too, don't want to depend on separate services.

I use TranscriptionSuite, which is focused on offline transcription, and supports Parakeet as well as whisper and others (https://github.com/homelab-00/TranscriptionSuite) The dev was sweet enough to improve the live mode GUI so that I and some friends can use it when playing on Chinese mmo servers.

As an Australian, Apples voice models have always sucked. I've tried using stt (again) more recently and its improved, but i'm so tired of having to Americanize my voice to get it to figure out what the hell i'm saying.

by verelo

7/13/2026 at 5:38:00 PM

As a Texan first, American second, I sympathize with this statement. Siri can't understand me probably 25% of the time. I use STT for iMessage while in the car, and half the time it will take 3+ times to either get it right or me give up, and hope to remember to text them by hand when I next stop.

by jermaustin1

Texans (generally) consider themselves Texans firsts. Similar to born and raised New Yorkers (NYC). That said, I really meant it tongue-in-cheek that my accent was too thick, and doesn't work well for Siri's STT model. ChatGPT's does way better, but I really don't like talking to an LLM.

Is parakeet state of the art? It always transcribes speech fragments for me, like if I stutter and say "m-m-m-map" parakeet will dutifully transcribe "m m m map". Which I guess could be a good thing or a bad thing depending on what you want. Whisper does not do that however.

I do like cohere transcribe a lot.

by ChadNauseam

7/13/2026 at 8:09:57 PM

I think that's parakeet doing its job there. That is a closer reflection of what you've actually said. The trick is then throwing that output through some additional deterministic and non-deterministic steps to tidy it up however you prefer. It's exactly what I do with my free and open source dictation app (dictator.robgough.net) for Mac+iOS. And of course, everything stays entirely on-device. Gemma E4B is really wonderful for that second step, it's great at language – but takes up 6-7GB RAM.

by robgough

7/14/2026 at 6:17:11 AM

Oh yeah, this one’s worth hyperlinking

https://dictator.robgough.net

Great work Rob! Indeed private as promised per App Privacy Report, “Domains contacted directly by app”:

  cas-bridge.xethub.hf.co; huggingface.co; mzstorekit.itunes.apple.com
Site could identify our device and send iOS visitors to the iOS page (or maybe that’s against the vibe and we should tap it ourselves).

App might be able to launch the keyboard settings directly but I suppose Apple doesn’t like devs using those undocumented URIs (uhg but maybe can understand part of it).

Keyboard, given manual app switchbacking + manual pasting, is less convenient for some of my use cases compared to an action button shortcut. (Reference Spokenly w/Local-Only Mode.)

Separating dictation and the history, and having a syncable scratch pad, are some welcome innovations!

>Gemma E4B … takes up 6-7GB RAM.

Google has a spyware-adjacent dictation app (maybe not really, but they demand to connect to servers after you enable their offline toggle). Just like yours, they thought of a cute name too (Google AI Edge Eloquent). Do you know what language model they install on the iPhone? Not a very good one but I’m sure over the next year or two…

by Barbing

7/14/2026 at 10:24:02 AM

I appreciate the kind words. Thank you.

I really wanted to have background audio and make it so the keyboard would directly record audio etc, but my first pass didn't make it through app review (and that was just keeping background audio listening AFTER you'd already started a recording). I could maybe have fought it, but figured if I was already butting up against app review there was little point as they'd likely reject in a future release anyway.

Re: analytics, It is quite weird having no idea how many people are using the app. It does leave you a little blind, but I figure people will get in touch if they have big enough problems with it.

For the Google app, I believe Gemma E2B and E4B both have audio input, so I suspect they're using one of those.

by robgough

7/15/2026 at 4:18:55 AM

Analytics: if you generate them on my device, and bury an option to manually send them to you when I have a bug--or...

you instead bury an opt-in to automatic telemetry, and let us CC ourselves each ~month when the analytics get sent in to you (so we can verify it's all boring data)...

It's hard for me not to opt in to stuff like that, at least periodically. If I'm opted-in by default? Ehhhhh.... I totally get it, weird "flying blind" (quoting a different dev w/similar philosophy), but I guess I'm still weird myself and hence looking for that autonomy or something? Oh and if somebody makes something opt in, and then certainly if they furthermore stick the option somewhere slightly off the beaten path, that seems pretty darn trustworthy.

(I wonder if we'd have enough public data for a decent statistician to calculate a likely number range of how many users you have by extrapolating from the 1% to 10% or 20% of users who'd chose to opt in...)

PS: "bury" concept likely not actually important :)

I use Parakeet V3 via this tool and it is actually quite reliable for me (in English): https://github.com/cjpais/Handy

by dinfinity

7/13/2026 at 7:55:04 PM

If you are using Parakeet for English only then you should be using V2. V3 is for several languages and is worse at English only.

by EsotericSoft

7/13/2026 at 6:04:00 PM

Agree on this point. Recent anecdotal testing I did found Whisper is still better than Parakeet.

by parentheses

7/13/2026 at 6:52:55 PM

Parakeet is certainly faster on my machine (m3 max), but I can't stand using it over Whisper for dictating my prompts. It makes a lot more mistakes, possibly because (like you mentioned) large portions of the speech will pause / stutter as I think about what to include.

With whisper v3 turbo, I can almost always live with the few mistakes because the overall stream-of-thought word-salad I provide is still clear at a high level. The bits and pieces of context seem to help, that I might leave out if typing and focused more on traditional conciseness / clean writing. With parakeet, I needed to do frequent editing even for shorter bits of speech.

I realize some applications prioritize the latency.

by obmelvin

7/14/2026 at 6:24:20 AM

The near-instantaneous nature of Parakeet has led me to keep using it and occasionally simply re-dictating a second time as needed.

For round two after a typo-laden transcript, I’m dictating and annunciating with great passion as I read the first transcript to make sure I don’t miss a beat. It’s kind of fun because it’s a little performance.

by Barbing

7/13/2026 at 6:58:39 PM

It sounds like post processing should be the job of an LLM. I would like the voice model to be faithful to what was said and then that output can be smoothed over or postprocessed as needed for the use case

by solenoid0937

7/13/2026 at 7:01:47 PM

To be clear, I'm talking about high word error rate with parakeet vs whisper, not post processing and cleaning up my speech. Re: being faithful to what was said, one small example, Whisper will often put ellipses when I pause.

by obmelvin

7/13/2026 at 5:01:30 PM

For multilingual and noisy audio the best right now is MOSS-Transcribe-Diarize which was released just a few days ago

Superwhisper does a lot more than just provide a whisper/parakeet UI so I’m not sure Apple will destroy them so easily

by wahnfrieden

7/13/2026 at 5:08:32 PM

Thanks, was looking at a better diarization model.

Even for those sorts of apps, MacParakeet which I've been using is FOSS so no payment needed. In reality these days with AI the ability to spin up a free and/or OSS competitor falls to zero.

by satvikpendem

7/13/2026 at 5:13:55 PM

I’m not even using it for diarisation just transcription and it’s amazing. It also doesn’t need a VAD

A new VAD I found though is FireRedVAD which has better benchmark results than TEN and Silero by far

by wahnfrieden

7/13/2026 at 9:08:51 PM

Is MOSS a streaming model or only for offline? For that VAD how are you integrating it into a model like Whisper etc?

by satvikpendem

7/13/2026 at 9:34:57 PM

I'm using it offline. But it's much faster than realtime so it should be usable for streaming. I just asked Codex / Sol to integrate FireRedVAD with Whisper...

by wahnfrieden

7/13/2026 at 6:51:09 PM

16GB! (edit: this is wrong, I was looking at TTS, the transcribe model is 1.7GB). Compared to Parakeet 2.3GB (but no diarization).

Also doesn't seem to be tailored to Apple hardware (i.e. no MLX or ANE variant/implementation)

by foobarqux

7/13/2026 at 8:28:46 PM

I am running the MLX fork https://huggingface.co/vanch007/mlx-MOSS-Transcribe-Diarize

Generally labs don't release MLX or ANE versions and we must rely on finding someone who's converted it

Parakeet is not multilingual so not directly comparable

Where do you see 16GB? MOSS is smaller than Parakeet at 1.82GB

by wahnfrieden

7/13/2026 at 8:45:51 PM

What's insane to me is that you have all of these low-quality me-too apps, and literally no one could bother to read the damn Human Interface Guidelines or follow iOS design conventions.

Doing so is literally LESS WORK than trying to make your own custom awful iOS UI.

by bellowsgulch

7/13/2026 at 6:48:03 PM

Not if your app is a Web wrapper, which so many of these are.

If you use SwiftUI (the native recommendation by Apple), it severely penalizes you, if you want to paint outside the lines (which is a big reason that I don't use SwiftUI for shipping apps). It's insanely easy to write a native app that is 100% in line with HIG.

by ChrisMarshallNY

7/13/2026 at 10:53:22 PM

Whisper v3 is still the best (by far) when it comes to poor quality input (say background audio from a security camera), though remains more susceptible to hallucination so it's a bit of a tradeoff.

by ComputerGuru

7/13/2026 at 7:00:14 PM

Yeah, apple will be optimizing a model to work on ANE and then turn it into a native app. My only hope is that it has a reasonable api so that I can use that as a generic input source across iOS / macOS that’s equivalent to the ubiquity of the keyboard.

by FuckButtons

7/13/2026 at 8:05:33 PM

Presumably the existing transcribe button on the keyboard will route through this on iOS 26?

by swiftcoder

7/14/2026 at 1:05:55 AM

One would hope, though I suspect they may want to make things a bit flashier than “we made the audio transcription on the keyboard not terrible” in the changelog given the amount of work that’s gone in.

by FuckButtons

7/13/2026 at 6:42:16 PM

> RIP to a lot of the paid apps that simply wrap Whisper

I started using a few open source apps for transcription and eventually subscribed to a paid one...

On paper, it's not hard to compete, but for this use case, a few rough edges make it really frustrating to use. Like a keyboard that sometimes doubles the letter "e"

Automatic dictionary, seamless language switch, no issues with accents, etc... Putting the effort in the last mile makes a world of difference.

If anyone has better options, I'm willing to have a look. The best open source solution I found was Handy, and I currently use Wispr Flow

by Adrig

7/13/2026 at 8:16:17 PM

I built my own because I was frustrated with a lot of the free options. Largely because a lot of them had an upsell to be able to do the secondary post-processing step with an LLM. And it wouldn't pick up things like emojis properly or say numbers. Because of that, I left quite a lot of options in there for customising and adding additional steps, etc. Feel free to take a look: dictator.robgough.net

My initial Mac version actually had three additional steps that you could toggle, obviously at the cost of some speed. That is what the website talks about, although nowadays for my own use I've reduced that to just one step and found that it's pretty great. I've got a new version in test to tidy that up, but still lets you define as many steps as you want.

Of these only Parakeet is <1B, it looks better than Apple's model, however it's not builtin. I wonder how it compares on latency and efficiency.

by orbital-decay

7/13/2026 at 6:34:15 PM

Parakeet is incredibly fast and accurate even on CPU, and it supports streaming now also in TDT3.

by hendersoon

7/13/2026 at 6:41:26 PM

Apple likely needed a model that ran on their NPU natively.

- parakeet usually runs on Bfloat16. NPU doesn't support that

- CPU is not as fast as the NPU for these ops on A-series, and even on modern CPUs, there's a latency delay

- Parakeet latency is fine but "fine" may not be good enough for Apple's UX team.

- CPU increases power consumption over dedicated float blocks

So I would say that Parakeet was a non-option for Apple to ship, although it should be in the benchmarks anyways!

Fluidaudio implements Parakeet on ANE. I'd like to know how SpeechAnalyzer compares in speed.

https://github.com/FluidInference/FluidAudio

by foobarqux

7/13/2026 at 11:35:02 PM

Recently contributed a patch to FluidAudio that sped up Parakeet V2 and V3 to 320x and 282x faster than real time, respectively:

https://github.com/FluidInference/FluidAudio/pull/507

That means one hour of audio transcribed in 11.25 and 12.75 seconds.

The Inscribe post doesn't give a speed factor for SpeechAnalyzer. However, this Argmax blog post reports 70:

https://www.argmaxinc.com/blog/apple-and-argmax

Based on that, FluidAudio is ~4.6x and ~4.0x faster.

by hamza_q_

7/14/2026 at 2:41:16 AM

The difference using an mp3 seems to be smaller: yap seems to use about the same time but fluidaudio seems to take twice as long. Do you happen to know why?

by foobarqux

7/14/2026 at 8:31:59 AM

Investigated this and it turned out to be an amusing bug: audio decoding was happening three times instead of just once lol. I've put up a PR to remove the wasteful redundant decoding:

https://github.com/FluidInference/FluidAudio/pull/799

With the updated PR code, ran a test comparing transcribing (using Parakeet V3) a 1 hr stereo 44.1 kHz mp3 vs the same audio in 16 kHz mono wav format. The result was about 21.3% slower with the mp3 vs the wav, i.e. that's the overhead of decoding + resampling.

Currently the decoding + resampling is done up front. If it was done in a pipelined fashion with the inference, that overhead can be eliminated. This is what I did in a recent app I made:

https://apps.apple.com/us/app/drea-podcast-ad-blocker/id6759...

It uses FluidAudio as well, but I forked it and replaced the audio decoding code to (a) use mpg123 instead of the native Apple API and (b) do audio decoding and inference in a pipelined fashion. These two changes effectively eliminated the overhead. mpg123 is quite a bit faster than the native Apple API at mp3 decoding (has some very optimized arm64 assembly routines), and the pipelining ensures that the inference is never starved by the mp3 decoding.

Contributing this pipelined setup to FluidAudio would be good.

by hamza_q_

7/14/2026 at 3:49:19 PM

That app was exactly what I was looking for, something like SponsorBlock but for podcasts but I suppose using AI for finding the ads works too. Any chance it'll release on Android?

by satvikpendem

7/14/2026 at 5:10:36 PM

Yep it's something I wanted for a while too; there were existing apps that did this, but had two issues: they were paid, and the UI was subpar. So for mine, I made sure it's fully free and that the UI is on par with Apple Podcasts, Spotify, etc.

Making the ad-finding cheap enough such that I could make it free turned out to be harder than expected. The main issue you run into is dynamic, location-targeted ads. So I came up with a novel technique that uses Shazam-style audio fingerprints for accurate matching, instead of their normal use case, which is identification. This technique is what allows the ad finding to be very cheap, allowing me to make it free.

The SponsorBlock model would actually not work for podcasts, due to dynamic ads. I.e. the location and content of the ads in episodes these days varies by download location. You need the media to be static, like YouTube, for SponsorBlock model to work. Therefore, using an LLM to find the ads + the fingerprints matching in combination is an efficient technique.

Android has def been the most requested thing thus far haha. It'll be a decent undertaking due to me having written the app fully in Swift, i.e. it'll be a complete rewrite. I'll also need to replace FluidAudio with some good, fast Android equivalent.

The goal of making this app was to create something impressive so that I could get a job. Haven't gotten a job yet, but if and when I do, then I'll have time & resources to think about doing an Android version. Currently a bit stressed and occupied from the job search lol.

by hamza_q_

7/14/2026 at 4:05:07 PM

Thanks!

I use fluidaudiocli and it's unfortunate that it doesn't support streaming (e.g. from a named pipe); that would have been an easy workaround to both the pipelining problem and the faster-decoder problem.

by foobarqux

7/14/2026 at 5:28:41 PM

Yep, agreed, streaming would be great to have. Although via pipes I think is better suited for a macOS. Since FluidAudio has to support both macOS and iOS, I think using Swift concurrency primitives would be the better fit. That's what I did for my app (TaskGroup, actor, AsyncSequence).

by hamza_q_

7/13/2026 at 7:12:24 PM

7/13/2026 at 7:18:20 PM

I don’t know how Apple divides computation between the GPU and the Neural Engine, but one major benefit, especially for real-time transcription on laptops, is the improved power and thermal efficiency. I noticed better accuracy after switching my app to SpeechAnalyzer, and I suspect part of that improvement for me came from the microphone no longer having to compete with jet-engine fan noise.

by sidkh

This particular product used Whisper, so that was obviously the right model to compare it against. Further this is explicitly on device, and Nemotron 3.5, as one example, is 2.5GB for the model.

And if someone were broadly comparing all on-device models (instead of just looking at how this new on-device ones compares to what a specific product uses), Nemotron 3.5's WER are actually a bit higher than what they report for SpeechAnalyzer, for both tests.

by llm_nerd

7/14/2026 at 11:55:45 AM

Being Apple’s model, it will support like 8 languages and leave the rest hanging for 10 years, just like Apple impotently ignored 10 or 20 million countries even with basic “just download open dictionary and run a deploy script” keyboard autocomplete.

The canadian government will provide lots of historical data for curious citizens, many of which are recordings of interviews from decades and decades ago. For a book project this allows me to make a hours of audio searchable through a GUI application I have developed that has a voxtral backend.

Just ran it against Whisper-Large-V2 on a math lecture (my primary use case for ASR is subtitling math lectures), and it was substantially faster and only slightly worse. Very usable for live transcription though I'll probably stick with whisper for the time being since I don't really need the subtitles to be generated in real time.

by ashivkum

7/13/2026 at 4:54:56 PM

Been using it for a podcast app I have been developing for half a year lol (I hope I publish it by version 27) and I can confirm it’s real fast.

Splitting the audio in multiple segments and firing it up without hitting the maximum limit of concurrent decoding streams makes it blazing fast. Fair enough you loose the cut, but it’s good enough for just podcast. In one minute it chews through one hour of audio. This on an iPhone 17 Pro.

by seviu

7/13/2026 at 7:51:20 PM

You could perhaps run over the segment splitting points (plus a few seconds back and forward) in a second batch then merge the results in the end so you don't miss anything.

by satvikpendem

Nothing really, except that I get to play with SpeechAnalyzer APIs, foundation models, translations. It’s basically my playground where to try all things. Been listening a lot of Chinese podcasts lately, transcribed and translated by local models.

Edit: all that said, the app is irrelevant. What I want to say is that live transcripts on iOS using Apples frameworks works very well. Only thing I miss is diarization support.

I will plug Willow for mac recording. IMO it's basically to me a "better than perfect transcription" as it cleans things up and is almost instant. I liked Superwhisper but switched to Willow as it was a big difference.

Its so good that I'm not sure that it's possible to get any better. Speech to text seems like basically a solved problem, if not now then definitely in 5 years. I don't know if any of these speech to text businesses will work in the long run, but for consumers they are great. My guess is the 2030 version of Apple's SpeechAnalyzer will be so good that nobody will need to use 3rd party software.

by mchusma

7/13/2026 at 11:42:07 PM

What isn't solved is domain-specific jargon with these tools. When i talk to my coding agent, i want to be able to speak the names of symbols and files and have it be aware of that stuff, like having LSP integration.

If I say 'useSuspenseQuery' I want it to come out as useSuspenseQuery not 'use suspense query'. Even if I had to say 'symbol useSuspenseQuery' to give a hint that i'm referencing a symbol, that would be fine.

Vs Voxtral would be a better comparison. No other model, open or closed, has been able to hit such a low AER (Acronym Error Rate ;)) for my meeting transcripts. Seems to understand/infer all the technobabble I use at work. Never have to edit anything. Whisper was catastrophically bad.

by summarity

I typically disable autocorrect on Apple products because of this, cautiously optimistic about their improved speech models, but definitely worried that it's going to 'correct' technical jargon to more common words.

by pants2

7/14/2026 at 1:47:21 AM

One tangible thing this doesn't touch on: SpeechAnalyzer supports streaming, so you can see what it's hearing from you as you talk. A massive UX improvement. Many of the other models force you to record, then it transcribes the audio to text as a single job, then returns the entire blob of text. It's slow, and frustrating if you're talking, only to realize it stopped listening after 2 minutes.

by mvkel

7/14/2026 at 6:40:11 AM

Just this week I built a live subtitles app for my mother in law who is hard of hearing (she has a hearing aid but still has trouble decoding, but can still read faster than me)

So I ended up organically testing and ending up with SpeechAnalyzer because it was not only fast and accurate enough, but you also see live results as you talk. It also has speaker identification and people can register their voices. And it does all processing on device.

It also had the best model for Indian accented English, given she lives in India.

So I was quite impressed, but the holy grail to me is transcription that does speaker identification but also works in a standard family conversation, where multiple people interrupt each other all the time.

I will say though, I'm really curious as to what Claude Code Desktop uses for their voice mode, because it seems even better than Apple's, and it provides realtime feedback. Maybe they're using apple's model?

Finally. I‘d be delighted though if they actually implemented language autodetection (like everywhere else) though. There’s little more frustrating in my day to day than having dictated half a page to find that it‘s complete gibberish because Apple forces you to select the right language first…

by endymi0n

7/13/2026 at 6:53:38 PM

Same with the keyboard. Apple is completely incapable of taking context into account for the input mechanisms of the operating system.

If I start typing and the existing text is in Spanish, then a sensible default is to select the Spanish keyboard I have installed and let me adjust otherwise.

App developers should also be allowed to supply mini-dictionaries within a context to allow autocorrect to work correctly in that context, so for example in this thread [SpeechAnalyzer, API, Whisper, Parakeet, Nemotron] should be supplied so that these terms are autocorrected.

by satvikpendem

I make an iOS app that uses this API heavily for transcribing diverse audio of varying bitrate and recording quality. The audio often contains music, multiple speakers, sound effects. SpeechAnalyzer almost always gets it.

It can struggle with proper nouns but will return something phonetically similar.

My main gripe is that it requires a separate model download per language. I understand the why they did this (to save disk space). But it makes multi-lingual audio hard to transcribe unless you know ahead of time the languages in the audio.

As an app developer the biggest win from using Apple's model is I don't have to bundle it in my app so my app looks much smaller. If a user has many transcription apps each one could have their own model. If Apple's model is used only one copy is needed.

For just desktop, I use Handy (open source): https://handy.computer/

And yea, Nvidia's Parakeet v3 is good enough for my own just local transcription most of the time.

When I need local transcription to be more reliable and I don't have the energy to proof read a long ramble, I still often just pop open chatGPT, dictate, cut, paste.

But we're pretty much already to the point where local transcription models can replace cloud ones for personal use. They're still a bit rough around the edges in terms of polish and latency, but plenty of people are fine with that to avoid yet another app subscription and not having to worry about wondering what's potentially happening with their data.

I have implemented this into Home Assustant some months (https://github.com/FI-153/wyoming-apple-stt). I find the comparison with Whisper particularly helpful since it is the base model used in Home Assistant to transcribe voice in the Assist pipeline. I find Whisper too heavy to run locally with good quality, SpeechAnalyzer instead comes bundled in macOS and is always available.

by Freddy153

7/13/2026 at 4:55:48 PM

Any chance you can benchmark against whisper large and large v3 turbo? These run comfortably on older Macbooks and are still far more accurate in real life dictation compared to even the parakeet models( despite ASR leaderboards) with an RTF < 1.

I'm always confused by these phrases:

> The new API cuts word error rate by 3.5 to 4x on the same audio: from 9.02% to 2.12% on clean speech

Shouldn't they have said "cuts error rate by 78%" or something?

by dclowd9901

7/13/2026 at 7:16:47 PM

I don’t like it written that way either, and it always seems like the type of number you put on a slide for a head of sales or something. It rankles because:

- it implies that error could be increased n-times, but a 15x _increase_ in 9% error would be an error rate of 135%, which is nonsensical.

- a reduction from 90% error to 20% error is clearly a bigger improvement in rightness to a reduction from 9% to 2%. One is “almost all wrong to almost all right”, the other is “more right”, but they are both a 4.5x reduction in error which means that the 4.5 quantity doesn’t have a constant meaning.

The answer is something like log odds ratios, but that introduces the additional need for a reader to know what that is, and that would be unusual.

I didn't expect Apple's SpeechAnalyzer to see such an impressive improvement. However, Whisper's biggest moat remains its cross-platform availability and support for 100+ languages. It would be awesome if SpeechAnalyzer could match that level of platform and language coverage.

Im hoping Apple gets the new Siri working better on older phones. I was excited to use it but the latest beta / Siri runs too slow on my iPhone Pro Max 15.

Im looking for the same experience I have when talking to chatGPT. As for past two years or more talking to GPT within it's app and on my iPhone Pro Max 15 it runs smooth as butter :-). This is the experience I was and still am hoping with Apple, but Im thinking all the extra layers of privacy and security might be slowing them down?

Overall, Apple who is suing Open AI should just buy them and let me have the best conversational AI out there baked into my old ass iPhone. Because as so far the new Siri on my old phone (tho again GPT works great talking to it and for years) doesnt come close. It's the same old "Could you try that again," Siri. BOO!!!

by paul7986

7/13/2026 at 4:39:09 PM

Yeah, ChatGPT voice is great experience vs. Siri on that phone. In case you haven't done something like this already:

  1. In Shortcuts app, make shortcut named "AI Voice Mode" (or whatever you want, YMMV)
  2. Set it to run the ChatGPT action "Voice Mode" (requires at least the minimum paid tier, I think)
  3. To trigger, say "Hey Siri, AI Voice Mode" (or whatever you called the shortcut)
This is a pretty slick integration, but yeah, if it were baked in that would be all the better.

by realityfactchex

7/13/2026 at 4:49:57 PM

Ridiculous that for past many years we can talk to GPT on our iPhones without any hiccups and this new Siri is still the same old horse crap (at least for me and this latest beta). Buy them already Apple or possibly be replaced by them as their path & trajectory (working on Ai devices now and they are stealing like Jobs did with Xerox) mirrors yours in the late 1970s.

Thanks for the tip and if Im not mistaken it's similar to asking Siri to ask chatGPT to ask XYZ?

by paul7986

7/13/2026 at 5:07:51 PM

> similar to asking Siri to ask chatGPT to ask XYZ

Effectively, it sort of does that, but really it just listens to the wakeword and opens/switches to the requested app & modality.

FWIW, I get a very different functional result using the Shortcut method vs. asking Siri to delegate natively. To compare, I asked Siri (non-beta here) now to "ask ChatGPT <x>" and I got a top-card with some fairly low quality SEO-ranked weblinks.

I’m on iPhone 17 Pro Max, 27 beta 3.

New Siri is impressive in that it answers satisfactorily now 80% of the time vs 10% with old Siri.

But it’s slow as shit. GPT, Claude, and Gemini can answer me in 5-10 seconds. Google AI Mode can answer in 2 seconds.

New Siri usually takes 25 seconds to respond to me. This morning it timed out (with strong network connection) when asked a simple multiplication question.

For my current purposes, I need a speech-to-text model/API to also emit word-level timestamps - for now, that makes ElevenLabs's Scribe v2 the best multiplatform, multi-language choice though it does look like this SpeechAnalyzer API provides them (although only for English).

by sudb

7/14/2026 at 7:18:05 AM

The article just says that SpeechAnalyzer size is "system." It actually treats each locale like an on-demand resource and Apple doesn't document how much space each one takes up or under what circumstances they get cleared.

In my own tests a few months ago, it was faster than both small/large Whisper models I compared it to with accuracy competitive with both of them (each model had different quirks).

Obligatory mention of Handy which is open-source and cross-platform:

It's great for me when configured to use Parakeet v3.

If you are running ios 27 beta is this the model when you hit voice to text on the native keyboard?

It’s a great API. I use it in my app and it’s feels so much more accurate.

Would this end up replacing the default iOS keyboard dictation functionality in iOS 27?

by akurilin

No, this is the current dictation functionality on iOS 26.

This is great marketing, I had no idea what inscribe was, but a blog like this going viral did something no ad could do for me.

this is amazing. if i had a mac i would try to reverse engineer the code, extract the weights and port it to something that works on linux/windows like torch or burn. then put the code on github and weights on a torrent site. lifes too short to let apple keep their models exclusive.

Aside from the legality of it, I think you are underestimating how complex it can be to do that. It is possible in theory but not something that will be a fun side quest like you are making it seem.

by altmanaltman

7/13/2026 at 4:54:07 PM

With a IDA Pro decompiler license & MCP server, paired with Codex/Claude Code... it would be a fun side quest.

You likely don't need to disassemble the inference code, the weights are "just an array of numbers" in MLX format.

This.

The Jedi Hand Wave-y nature of the way people talk about AI these days is going to make reigning in the AI superpowers nearly impossible. Because there are people out here who believe models of this quality are easily replicated or reverse engineered. Neither is really doable on any reasonable timeline by people who are not AI experts. Real AI experts. Not TF/PyTorch monkeys or Agent Slop Slingers.

And those people are already highly incentivized to not make anything performing better than SOTA models open source.

Probably not worth the effort (or legal trouble), unless you can show it's better than other recent open models like Cohere Transcribe.

Is that copyright infringement?

by kridsdale1

7/13/2026 at 4:45:12 PM

This hasn't been tested in court. But there's a high chance that model weights are not copyrightable, only the code to generate them is.

Cloud models are usually protected by trade secret laws, leaking them would get you in trouble. However if the model is made available publicly, as long as you don't break the law to get them, anything after that would be fair game unless Apple can prove that humans have significant authorship over the weights, which hasn't been tested and is a significant burden to prove/disprove.

by nodja

7/14/2026 at 7:01:13 AM

So the models will be protected by contact law instead. Can you get an apple update without agreeing to the iOS terms?

by efreak

7/13/2026 at 5:11:20 PM

Copyright protects original forms of expression, not arbitrary data. It is very arguable whether it applies to model weights. However, it would likely constitute a license violation.

I wish Apple would update there built in TTS model (on Mac). In this day and age, it's quality is terrible.

Still nothing beats OpenAI's VTT. Anthropic's sucks and Apple's isn't even usable.

Edit: Getting downvoted by Apple fanboys for telling the truth is a badge of honor.

Which OpenAI model/API do you mean?

by simonw

Whisper and GPT-4o (for diarization).

7/13/2026 at 4:45:45 PM

In which world 98% accuracy is not usable?

by nicce

7/13/2026 at 4:46:58 PM

In a world where you say "tmux" and Apple's VTT writes "T Max".

by behnamoh

7/13/2026 at 5:46:00 PM

You can't reasonably expect generic ASR to infer tmux from "tee-mucks". "tee-em-you-ex" works reliably if you're ok with capitalisation for your use case.

Author here. I ship both Apple speech engines plus WhisperKit side by side in a transcription app, which made it possible to run all five through identical production code on the same audio: LibriSpeech test-clean and test-other, 5,559 utterances, fully on-device on an M2 Pro.

Apple published no accuracy numbers for SpeechAnalyzer (or for SFSpeechRecognizer, ever, as far as I can tell), so the migration question has been guesswork. Short version: the new API cuts WER 3.5-4x vs the old one (2.12% vs 9.02% on test-clean), and it also beat Whisper Small on both splits at about 3x the speed. The old API came in last on clean speech, behind even Whisper Tiny.

On "why should I trust a vendor benchmark": the Whisper column reproduces OpenAI's published LibriSpeech WERs within +0.11 to +0.42 on all six measurements (same corpus, same normalizer, same scorer for every engine), and the raw per-utterance transcripts are downloadable from the article if anyone wants to rescore with their own normalizer.

Limitations worth stating up front: English only, read speech rather than meeting audio, one machine. Precise per-engine timing isn't in the article yet because the accuracy runs shared the machine with a dev workload; WER is load-independent, timing isn't.

Two things that might interest people migrating: SFSpeechRecognizer sends audio to Apple's servers unless you set requiresOnDeviceRecognition, and with SpeechAnalyzer, finishing your input stream is not enough to end a session. If you never call finalizeAndFinishThroughEndOfInput(), the results sequence never terminates and your await hangs forever. I found that one because it was shipping in my own app.

Happy to answer questions about the harness or the normalizer.

At this point, I would not recommend ignoring Parakeet TDT 0.6b v2/v3 (english-only versus multilingual). Those models have been out for a year, give or take, and they are both accurate and fast. I would choose Parakeet over Whisper in almost all situations these days. Parakeet works great even on my several year old iPhone 15 Pro Max, so if an app is going to ship a dedicated model, I strongly recommend investigating Parakeet.

On the more cutting edge front, Granite Speech 4.1 has proven to be a reliable workhorse for me, but it is larger than Parakeet. Cohere Transcribe is interesting, but how strong it is seems to vary more from task to task.

Parakeet Unified 0.6B came out a few months ago, combining both online streaming and offline transcription into one model, and that is one that I need to test more, but it seems promising.

As others have mentioned macOS 27/iOS 27 is supposed to have a new model, particularly on devices with 12GB of RAM or more. I have not actually seen the option to enable that new model yet, though, despite being on the beta on a device that meets the requirements. Maybe a benchmark would reveal that it is already active?

by coder543

7/13/2026 at 5:06:06 PM

Why do you not use Whisper large models when on macOS? They're still fast even when streaming and yield a much lower WER.

Also, just out of curiosity, seems like everyone and their mother is making Whisper wrappers, how is your app different?

Why use relatively ancient models like whisper and not e. g. parakeet?

If this isn't open source/weights and can't run locally, I don't see how this is a replacement for Whisper or other open models, e.g. within Home Assistant.

by drnick1

7/13/2026 at 4:57:52 PM

It's a local model so it's essentially open weight such that you could feasibly export it somehow since it's already on the laptop somewhere. Apfel is a wrapper app like ChatGPT but using Apple Foundation Models, I assume something similar will happen with this transcription model.

https://apfel.franzai.com/

by satvikpendem

7/13/2026 at 5:00:46 PM

It's not open weight, but the point is to be an on device (and thus local, privacy preserving) option. The article mentions that as the caveat

> What this means if you just want good transcription

> If you are on a current iPhone or Mac, the best on-device transcription engine for English is already in the operating system, and the private option is no longer the compromise option

by edude03

7/14/2026 at 12:16:52 AM

If already have current Mac or iPhone, and thereby implictly "trust Apple", then why would one need a "a local, privacy-preserving" option

If trust Apple, then no need for privacy from Apple

How can you be sure this isn't leaking data or metadata to Apple? Can Apple really be trusted?

by drnick1

7/13/2026 at 7:52:38 PM

The article states:

> If you are on a current iPhone or Mac

Presumably if you don't trust apple you wouldn't purchase their products and even if you were for example forced to use it via work or something you wouldn't use this feature ... so it doesn't really change the calculus as presented by this article - IF you ALREADY HAVE a MODERN Mac (and trust apple) this is your best option

Test it! Does it make network requests? Unplug the internet and see if it still works!

by madeofpalk

7/13/2026 at 7:06:28 PM

You are being naive. An Apple device makes dozens of network requests every minute or so to Apple. It is neigh on impossible to verify what is being requested or sent. Also unplugging the Internet and verifying that something still works does not mean the app won't phone home behind your back when it can. These things are designed to fail silently.

Download use Little Snitch or

https://alternativeto.net/software/little-snitch/

https://www.g2.com/products/little-snitch/competitors/altern...

There are many alternatives for trying to find out what’s going on. If you don’t want to bother, and most people don’t, well, what else is there to say?

It is generally a good idea to know what software is phoning home, if you can pinpoint it.

If you have any software recommendations, I’d be happy to know.

by Danox

7/13/2026 at 10:42:26 PM

It's more complex than that. LittleSnitch or other application firewalls won't help when programs like package managers legitimately need to access the Internet. And figuring what what is being sent would require decrypting the traffic. There is no easy way to figure out if Apple or some rogue app is siphoning off your home directory.

by drnick1

7/14/2026 at 12:17:41 AM

This is Hacker News. Computers are knowable, tractable things. It is trivial to know if a process is making network requests.

by madeofpalk

7/14/2026 at 2:41:14 AM

It's definitely not trivial to figure out what for, and what is being sent or received.

by drnick1

7/13/2026 at 5:06:08 PM

It is local

The appeal is that users only have to download it once across all apps that use it. Instead of convincing a user to give a couple gigs for just your one app
