Whisper transcribes and translates speech with solid accuracy across languages and accents, and its weights are open, so teams self-host it to avoid per-minute API fees. Variants like faster-whisper and WhisperX add speed and extra features.

AI for Video: A Complete Guide to Intelligence in Video Products: From Models and Inference to Computer Vision, Speech, Search, and Generative Video
Whisper is the default free baseline for transcription, but hallucinations on silence and slow decoding catch many teams in production. Volume 6 covers Whisper in detail within speech AI: ASR models and vendors, faster variants, diarization, word timestamps and the deployment choices between self-hosting and APIs. Written by Nikolay Sapunov, CEO at Fora Soft.
