I thought whisper and others took large chunks (20-30 seconds) of speech, or a complete wave file as input. How do you get real-time transcription? What size chunks do you feed it?

To me, STT should take a continuous audio stream and output a continuous text stream.

    I use VAD to chunk audio.

    Whisper and Moonshine both works in a chunk, but for moonshine:

    > Moonshine's compute requirements scale with the length of input audio. This means that shorter input audio is processed faster, unlike existing Whisper models that process everything as 30-second chunks. To give you an idea of the benefits: Moonshine processes 10-second audio segments 5x faster than Whisper while maintaining the same (or better!) WER.

    Also for kyutai, we can input continuous audio in and get continuous text out.

      Having used whisper and noticed the useless quality due to their 30-second chunks, I would stay far away from software working on even a shorter duration.

      The short duration effectively means that the transcription will start producing nonsense as soon as a sentence is cut up in the middle.

      Something like that, in a cli tool, that just gives text to stdout would be perfect for a lot of use cases for me!

      (maybe with an `owhisper serve` somewhere else to start the model running or whatever.)

FYI: owhisper pull whisper-cpp-large-turbo-q8 Failed to download model.ggml: Other error: Server does not support range requests. Got status: 200 OK

But the base-q8 works (and works quite well!). The TUI is really nice. Speaker diarization would make it almost perfect for me. Thanks for building this.

Sorry, maybe I missed it but I didn't see this list on your website. I think it is a good idea to add this info there. Besides that, thank you for the effort and your work! I will definetely give it a try
