Ask HN: What Speaker Diarization tools should I look into?
I am making a tool that needs to analyze a conversation (non-English) between two people. The conversation is provided to me in audio format. I am currently using OpenAI Whisper to transcribe and feed the transcription to ChatGPT-4o model through the API for analysis.
So far, it's doing a fair job. Sometimes, though, reading the transcription, I find it hard to figure out which speaker is speaking what. I have to listen to the audio to figure it out. I am wondering if ChatGPT-4o would also sometimes find it hard to follow the conversation from the transcription. I think that adding a speaker diarization step might make the transcription easier to understand and analyze.
I am looking for Speaker Diarization tools that I can use. I have tried using pyannote speaker-diarization-3.1, but I find it does not work very well. What are some other options that I can look at?
