the on_realtime_transcription_update text issue

[jacobtang]

Hi,@KoljaB
I use the on_realtime_transcription_update(also try the on_realtime_transcription_stabilized) text,send to the web client,but it always show the pre text word.
Is there other method that can avoid show the repeated pre words?Thanks!

I try to implement live transcription function similar to Zoom Meeting in the product.

No, that ist due to the way Whisper works and how it therefore is implemented. You'd need to program this on top of that.

Ok,thanks a lot!
I use the process_text callback data, it costs about 3s to get the text data, is it normal? how should I reduce the time cost?
use the recorder_config,and recorder.feed_audio(audio_chunk) method in GPU env.

Absolutely not normal. Even with largest model or on CPU transcription time should be way below 1s.
I have no real idea, why this happens.
Can you please try another model, like small.en or medium? Also a separated test with only faster_whisper library could tell us if it's the transcription or maybe something related to the VAD models.
