Speech-to-text is the quiet workhorse of AI workflows: transcripts, subtitles, meeting minutes, voice commands. The local options are now excellent.

The Three Tools

Whisper (106,813 stars) is the accuracy baseline: 99 languages, robust to noise, but slow on CPU. faster-whisper (24,790 stars) reimplements it on CTranslate2 for 4x speed with near-identical accuracy. FunASR (19,708 stars) is the Chinese-optimized toolkit from Alibaba - punctuation and timestamps out of the box, excellent for zh audio.

How to Choose

Language-agnostic accuracy: Whisper large-v3. High volume on modest hardware: faster-whisper. Chinese-first production: FunASR. All run fully local, so transcripts of sensitive calls never leave your machine - a decisive factor for legal and medical use.

FAQ

Q: What is the accuracy on accented English?
A: Whisper large-v3 handles accents well; small models struggle - test your exact audio before committing.

Q: Can I get speaker labels?
A: Whisper alone cannot - add whisperX (23,466 stars) for diarization, or FunASR for Chinese speaker separation.
