AI for Video: A Complete Guide to Intelligence in Video Products: From Models and Inference to Computer Vision, Speech, Search, and Generative Video
Speaker diarization is what turns a meeting transcript into a readable conversation, and overlapping speech is where it fails most often. Volume 6 covers speaker diarization in detail within speech AI: ASR, TTS, diarization engines such as pyannote, transcripts as searchable data and the deployment choices between batch and near-live processing. Written by Nikolay Sapunov, CEO at Fora Soft.
