What it is

stable-ts tackles Whisper's weakest point — word-level timestamp drift — by re-running inference with a tuned segmentation strategy. The result: noticeably cleaner SRT/VTT output for subtitles and shorts. Pairs well with whisper.cpp or faster-whisper as the underlying engine.

Best for: Subtitle generation where drift and poor word boundaries matter.
Watch out for: Slower than faster-whisper; no diarization; less community momentum than whisperX.
