## What it does

Adds forced alignment and diarization on top of Whisper so you get accurate per-word timestamps and speaker labels. Most transcript-first editing skills rely on this kind of output to place cuts between words and time captions word by word.

## Use when

- word-timed captions
- cut on word boundaries
- label who speaks when in interviews

## Install

- Claude Code: `pip install whisperx`
