According to the OpenASR Leaderboard [1], looks like Parakeet V2/V3 and Canary-Qwen (a Qwen finetune) handily beat Moonshine. All 3 models are open, but Parakeet is the smallest of the 3. I use Parakeet V3 with Handy and it works great locally for me.

[1]: https://huggingface.co/spaces/hf-audio/open_asr_leaderboard

Parakeet V3 is over twice the parameter count of Moonshine Medium (600m vs 245m), so it's not an apples to apples comparison.

I'm actually a little surprised they haven't added model size to that chart.

parakeet v3 has a much better RTFx than moonshine, it's not just about parameter numbers. Runs faster.

https://huggingface.co/spaces/hf-audio/open_asr_leaderboard

That was my experience when I tried Moonshine against Parakeet v3 via Handy. Moonshine was noticeably slower on my 2018-era Intel i7 PC, and didn't seem as accurate either. I'm glad it exists, and I like the smaller size on disk (and presumably RAM too). But for my purposes with Handy I think I need the extra speed and accuracy Parakeet v3 is giving me.

It is about the parameter numbers if what you care about is edge devices with limited RAM. Beyond a certain size your model just doesn't fit, it doesn't matter how good it is - you still can't run it.

So I'm kinda new to this whole parakeet and moonshine stuff, and I'm able to run parakeet on a low end CPU without issues, so I'm curious as to how much that extra savings on parameters is actually gonna translate.

Oh and I type this in handy with just my voice and parakeet version three, which is absolutely crazy.

Was a big fan of Handy until I found Hex, which, incredibly, has even faster transcription (with Parakeet V3), it’s MacOS only:

https://github.com/kitlangton/Hex

I tried this out but the brew command errors out saying it only works on macOS versions older than Sequoia.

That's unfortunate. I think I can update my version but I have heard some bad things about performance from the newer update from my elder brother.

> I tried this out but the brew command errors out saying it only works on macOS versions older than Sequoia.

Newer than Sequoia, you mean?

The brew recipe [1] says macOS >= 15.

Anyway, I'm on Sequoia — it's mostly better than Ventura, which was what my M2 MacBook Pro came with. I'm holding off upgrading to Tahoe (macOS 26), hoping they fix liquid glAss.

works fine on my MacOS w Tahoe

Handy is amazing. Super quality app.

It really is. It's kinda ridiculous that it's free.

I'm quite surprise to see that level of polish from an open-source project.

Are voice or a transcript sent back to their servers? If so, you may be the product

No, it's just somebody's open source project: https://github.com/cjpais/handy

By the way, I've been using a Whisper model, specifically WhisperX, to do all my work, and for whatever reason I just simply was not familiar with the Handy app. I've now downloaded and used it, and what a great suggestion. Thank you for putting it here, along with the direct link to the leaderboard.

I can tell that this is now definitely going to be my go-to model and app on all my clients.

I have to ask- I see this handy app running on Mac and you hold a key down and then it doesn't show until seemingly a while later.

The one built in is much faster, and you only have to toggle it on.

Are these so much more accurate? I definitely have to correct stuff, but pretty good experience.

Also use speech to text on my iphone which seems to be the same accuracy.

I'm building a local-first transcription iOS app and have been on Whisper Medium, switching to Parakeet V3 based on this.

One note for anyone using Handy with codex-cli on macOS: the default "Option + Space" shortcut inserts spaces mid-speech. "Left Ctrl + Fn" works cleanly instead. I'm curious to know which shortcuts you're using.

I am looking for such an app. Main use case is transcribing voice notes received on Signal while preserving privacy. Please post when you launch :)

why V3 over V2 (assuming English only)?

To this comment and all the other comments talking about handy below this comment. I tried handy right now and it's super amazing. I'm speaking this from Handy. This is so cool, man.

And handy even takes care of all the punctuation, which is really nice.

Thanks a lot for suggesting it to me. I actually wanted something like this, and I was using something like Google Docs, and it required me to use Chrome to get the speech to text version, and I actually ended up using Orion for that because Orion can actually work as a Chrome for some reason while still having both Firefox and Chrome extension support. So and I had it installed, but yeah.

This is really amazing and actually a sort of lifesaver actually, so thanks a lot, man.

Now I can actually just speak and this can convert this to text without having to go through any non-local model or Google Docs or whatever anything else.

Why is this so good man? It's so good

man, I actually now am thinking that I had like fully maxed out my typing speed to like hundred-120. But like this can actually write it faster. you know it's pretty amazing actually.

Have a nice day, or as I abbreviate it, HAND, smiley face. :D

hmmm looks like assembyAI is still unbeatable here in terms of cost/performance unless im mistaken

edit: holy shit parakeet is good.... Moonshine impressive too and it is half the param

Now if only there was something just as quick as Parakeet v3 for TTS ! Then I can talk to codex all day long!!!

Also running parakeet on my phone with https://github.com/notune/android_transcribe_app

Very lightweight and good quality

This is actually pretty impressive. What kinda phone are you using? Are you noticing any drain on battery heat?Do you think it's possible to get this working with Flutter on iOS?

2-3 years old Android flagship phone with 8 GB RAM. When I looked for an app for parakeet, I think I also came across iOS apps. Don't recall it since I use Android. Seems light on the phone/battery. Don't observe any drain but I also only record shorter transcripts at once. Side note: Parakeet is actually pretty nice to do meetings with oneself. Did that on a computer while driving for an hour (split in several transcript chunks). Processed the raw meeting notes afterwards with an LLM. Effective use of the time in the car...

Parakeet doesn't require a GPU. I'm handily running it on my Ubuntu Linux laptop.

I'm looking to switch from feeding the default android "recorder" app's .WAV into Gemini 3 Pro (via the app) with (usually just) a `Transcribe this please:` prompt; content is usually German voice instructions/explanation for how to do/approach some sysadmin stuff; there does tend to be some amount of interjecting (primarily for clarifications(-posing/-requesting)) by me to resolve ambiguity as early as possible/practical.

If e.g. parakeet can be run on my phone in real time showing the transcript live:

- with latency low enough to be "comfortable enough" for the instructor to keep an eye on and approve the transcribed instructions

[not necessarily every word of the transcript, i.e., a commanded "edit" doesn't need to be applied in the outcome as long as it's nature is otherwise clear enough to not add meaningful amounts of ambiguity to the final "written" instructions]

by glancing at the screen while dictating the explanation (and blurting out any transcription complaints as soon as that's possible without breaking one's own string-of-thought or spoken grammar too much)

, I'd very happily switch to that approach instead of what I was doing.

Bonus if there's a no-bulky-or-expensive-hardware way to accommodate us both speaking over each other so I won't have to _interrupt_ his speaking just to put a clarifying comment (on what he just said) in the transcript for him to see and sign off, where the at least "only" briefly interrupts his thoughts right while he actually reads my transcribed words (he doesn't have to hear them, and it's better if he won't; I can probably get him to put on earmuffs to not hear me louder than he hears his thoughts, and a sufficiently-smoothed SNR meter for specifically his voice should take care him regulating his volume while the earmuffs mute it and I occasionally talk over him)...

LLM account

you are right i just downloaded it on handy and its working i can't believe it

i was using assmeblyAI but this is fast and accurate and offline wtf!

What's wrong with piper?

How much VRAM does parakeet take for you? For some reason it takes 4GB+ for me using the onyx version even though it’s 600M parameters

Congrats on the results. The streaming aspect is what I find most exciting here.

I built a macOS dictation app (https://github.com/T0mSIlver/localvoxtral) on top of Voxtral Realtime, and the UX difference between streaming and offline STT is night and day. Words appearing while you're still talking completely changes the feedback loop. You catch errors in real time, you can adjust what you're saying mid-sentence, and the whole thing feels more natural. Going back to "record then wait" feels broken after that.

Curious how Moonshine's streaming latency compares in practice. Do you have numbers on time-to-first-token for the streaming mode? And on the serving side, do any of the integration options expose an OpenAI Realtime-compatible WebSocket endpoint?

I've helped many Twitch streamers set up https://github.com/royshil/obs-localvocal to plug transcription & translation into their streams, mainly for German audio to English subtitles.

I'd love a faster and more accurate option than Whisper, but streamers need something off-the-shelf they can install in their pipeline, like an OBS plugin which can just grab the audio from their OBS audio sources.

I see a couple obvious problems: this doesn't seem to support translation which is unfortunate, that's pretty key for this usecase. Also it only supports one language at a time, which is problematic with how streamers will frequently code-switch while talking to their chat in different languages or on Discord with their gameplay partners. Maybe such a plugin would be able to detect which language is spoken and route to one or the other model as needed?

Claiming higher accuracy than Whisper Large v3 is a bold opening move. Does your evaluation account for Whisper's notorious hallucination loops during silences (the classic 'Thank you for watching!'), or is this purely based on WER on clean datasets? Also, what's the VRAM footprint for edge deployments? If it fits on a standard 8GB Mac without quantization tricks, this is huge.

Open-weight STT models hitting production-grade accuracy is huge for privacy-sensitive deployments. Whisper was already impressive, but having competitive alternatives means we're not locked into a single model family. The real test will be multilingual performance and edge device efficiency—has anyone benchmarked this on M-series or Jetson?

For those wondering about the language support, currently English, Arabic, Japanese, Korean, Mandarin, Spanish, Ukrainian, Vietnamese are available (most in Base size = 58M params)

Accuracy is often presumed to be english, which is fine, but it's a vague thing to say "higher" because does it mean higher in English only? Higher in some subset of languages? Which ones?

The minimum useful data for this stuff is a small table of language | WER for dataset

No idea why 'sudo pip install --break-system-packages moonshine-voice' is the recommended way to install on raspi?

The authors do acknowledge this though and give a slightly too complex way to do this with uv in an example project (FYI, you dont need to source anything if you use uv run)

Any plans regarding JavaScript support in the browser?

There was an issue with a demo but it's missing now. I can't recall for sure but I think I got it working locally myself too but then found it broke unexpectedly and I didn't manage to find out why.

> Models for other languages are released under the Moonshine Community License, which is a non-commercial license.

Weird to only release English as open weights.

I find it an even more weird practice for anyone working with speech or text models not in the first paragraph name the language it is meant for (and I do not mean the programming language bindings). How many English native speakers are there 5% of the world population?

Approximately yes, although another 15% are non-native English speakers. Chinese is a close second for total speakers.

Very exciting stuff!

    hear about what people might build with it

Due to the sector being increasingly worried about "hybrid threats" we try to rely on the cloud as little as possible and run things either on device or with the possibility of being self-hosted/on-premise. I really like the direction your company is going in in this respect.

We'd probably need custom training -- we need Norwegian, and there's some lingo, e.g., "bravo one two" should become "B-1.2". While that can perhaps also be done with simple post-processing rules, we would also probably want such examples in training for improved recognition? Have no VC funding, but looking forward to getting some income so that we can send some of it in your direction :)

Interesting. Can we get in touch? I just sold my webapp/saas where I used NB-Whisper to transcribe Norwegian media (podcast, radio, TV) and offer alerts and search by indexing it using elasticsearch.

Edit: It was https://muninai.eu (I shut down the backend server yesterday so the functionality is disabled).

Sure! I didn't find your contact info but drop me an email at dag@syncmap.no.

Nice work. One metric I’d really like to see for streaming use cases is partial stability, not just final WER.

For voice agents, the painful failure mode is partials getting rewritten every few hundred ms. If you can share it, metrics like median first-token latency, real-time factor, and "% partial tokens revised after 1s / 3s" on noisy far-field audio would make comparisons much more actionable.

If those numbers look good, this seems very promising for local assistant pipelines.

Tangentially, have you got any idea what the equivalent "partial tokens revised" rate for humans is? I know I've consciously experienced backtracking and re-interpreting words before, and presumably it happens subconsciously all the time. But that means there's a bound on how low it's reasonable to expect that rate to be, and I don't have an intuition for what it is.

I'm offering support for this in Resonant - Already set up and running this week.

It's incredible for a live transcription stream - the latency is WOW.

https://www.onresonant.com/

For the open source folks, that's also set up in handy, I think.

Is this alternative to Whispr Flow?

This is awesome, well done guys, I’m gonna try it as my ASR component on the local voice assistant I’ve been building https://github.com/acatovic/ova. The tiny streaming latencies you show look insane

If it's using ONNX, can this be ported to Transformers.js?

Which program does support it to allow streaming? Currently using spokenly and parakeet but would like to transition to a model that is streaming instead of transcribing chunk wise.

The streaming architecture looks really promising for edge deployments. One thing I'm curious about: how does the caching mechanism handle multiple concurrent audio streams? For example, in a meeting transcription scenario with 4-5 speakers, would each stream maintain its own cache, or is there shared state that could create bottlenecks?

Very cool. Anyway to run this in Web assembly, I have a project in mind

Oh this is fantastic. I'm most interested to see if this reaches down to the raspberry pi zero 2, because that's a whole new ballgame if it does.

I've been using Moonshine since V1 and the results are really great. I'd say on par with Parakeet V3 while working really well with CPU only.

I vibe-trained moonshine-tiny on amateur radio morse code last weekend, and was surprised at the ~2% CER I was seeing in evals and over the air performance was pretty acceptable for a couple hour run on a 4090.

haven't tested yet but I'm wondering how it will behave when talking about many IT jargon and tech acronyms. For those reason I had to mostly run LLM after STT but that was slowing done parakeet inference. Otherwise had problems to detect properly sometimes when talking about e.g. about CoreML, int8, fp16, half float, ARKit, AVFoundation, ONNX etc.

Streaming transcription is crazy fast on an M1. Would be great to use this as a local option versus Wispr Flow.

Do you also support timestamps the detected word or even down to characters?

Implemented this to transcribe voice chat in a project and the streaming accuracy in English on this was unusable, even with the medium streaming model.

How does this compare to Parakeet, which runs wonderfully on CPU?

onnx models for browser possible?

How does it compare to Microsoft VibeVoice ASR https://news.ycombinator.com/item?id=46732776 ?

fyi the typepad link in your bio is broken

The LICENSE file that refers to is missing. There's one in the python folder, but not for the rest of the code.

IANAL.

Presuming (I haven't checked myself) the git author information supports this, it should be fine to treat this as licensing the code it specifies under MIT; based on that license name being (to my understanding) unambiguous and license application being based on contract law and contract law basically having at it's very core the principle of "meeting of the minds" along with wilful infringement being really really hard to even argue for if the only thing that's separating it from being 100% clearly licensed in all proper ways being not copying in an MIT `LICENSE` template with date and author name pasted into it.
