What HN said

What people liked

  • Streaming latency is very fast, including on CPU and M1 hardware.

    From 4 comments
    • Streaming transcription is crazy fast on an M1. Would be great to use this as a local option versus Wispr Flow.

    • 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.
      dSebastien on HN
    • 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…

    • The streaming latency numbers are what stand out to me here. Accuracy benchmarks get all the attention, but for real-time applications (voice assistants, live captioning, in-call…

  • Competitive with Parakeet V3 for accuracy on CPU.

    • I think there is a streaming version of Parakeet. It is often referred to as Nemotron, though. I tried comparing Parakeet streaming with Moonshine streaming. Moonshine is…

Objections

  • Accuracy is weaker than Parakeet V3 in some tests and on streaming English.

    From 3 comments
    • 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…
      Karrot_Kream on HN
    • 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…

    • 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.

  • Non-English models are under a non-commercial license and only English weights are open.

    From 1 comment
    • > 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.
      RobotToaster on HN
  • Claimed accuracy lacks language breakdown and clear benchmark details.

    From 2 comments
    • 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?…

    • 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…

Requests

  • Add model size to the leaderboard comparison.

    From 1 comment
    • 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…

  • Support for browser, WebAssembly or ONNX.

    From 4 comments
    • onnx models for browser possible?
      sroussey on HN
    • Very cool. Anyway to run this in Web assembly, I have a project in mind
      999900000999 on HN
    • The Parakeet vs Moonshine debate here is missing the point imo. For anything server-side or desktop, sure, Parakeet wins on raw WER. But Moonshine at 245M params vs 600M+ is a…

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

  • Include a LICENSE file for all code.

    From 2 comments
    • No LICENSE no go
      cyanydeez on HN
    • The LICENSE file that refers to is missing. There's one in the python folder, but not for the rest of the code.

Questions

  • How does it compare to Parakeet?

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

  • Does it run on Raspberry Pi or phones?

    From 2 comments
    • 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.
      regularfry on HN
    • what is the system requirement? can it run on CPU only ? phones ? edit: This is actually amazing. I'm using handy and parakeet to type this message with just my voice. Wow.

  • What are the streaming latency and partial stability metrics?

    From 2 comments
    • 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…

    • 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…
