Hi,

I am looking for a fire and forget solution akin to whisper where I can give it a wav of around 12 people and it can give me a diarization on the format (speaker_1, speaker_2, etc)

whispercpp gives labels like speaker_turn which is not what I am looking for, I need to know who said what

nvidia nemo only works with 4 speakers and unfortunately is not good enough for me

Do you have an open source solution that you can suggest? Or a potential pipeline?

Much appreciated!

The author is seeking a 'fire and forget' open-source solution for speaker diarization that can handle audio files with around 12 speakers and provide a clear identification of who said what.
