AI for Video: A Complete Guide to Intelligence in Video Products: From Models and Inference to Computer Vision, Speech, Search, and Generative Video
Pyannote is the usual open choice for who-spoke-when, and overlapping speech is where diarization errors pile up. This volume covers Pyannote in its speech section: speaker diarization in production, voice activity detection, speaker embeddings, and pairing diarization with ASR such as Whisper. Written by Nikolay Sapunov, CEO at Fora Soft.
