About
WhisperX is an advanced automatic speech recognition (ASR) tool that significantly enhances OpenAI's Whisper model by providing accurate word-level timestamps and speaker diarization. It achieves impressive speeds, offering 70x real-time transcription using the large-v2 model with batched inference and a faster-whisper backend, requiring less than 8GB GPU memory. The tool utilizes wav2vec2 alignment for precise word timings and pyannote-audio for multispeaker ASR with speaker ID labels. Additionally, VAD preprocessing reduces hallucination and improves batching without degrading Word Error Rate (WER). WhisperX is ideal for transcribing long-form audio, particularly meetings, where accurate speaker identification and precise timing are crucial. It supports various languages and offers both command-line and Python usage for flexible integration.
