Evidence claims:
- [upstream_claim] README: fast ASR (70x realtime with large-v2) with word-level timestamps and speaker diarization; uses faster-whisper backend (<8GB GPU memory for large-v2 with beam_size=5), wav2vec2 phoneme-based alignment and pyannote-audio diarization. · locator: README, intro and features · source: https://github.com/m-bain/whisperX
- [sourced_fact] README: for GPU use install CUDA toolkit 12.8 first; GitHub: BSD-2-Clause, not archived, last push 2026-09-26. · locator: README, setup · source: https://github.com/m-bain/whisperX
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
