About WhisperX
WhisperX provides automatic speech recognition with word-level timestamps and speaker diarization. It is distributed as source code installed through PyPI and run from the command line. GPU use needs CUDA toolkit 12.8 installed first, and speaker labeling needs a Hugging Face read token and agreement to the diarization model terms.
Pricing is not clearly stated.
