linto-ai/whisper-timestamped

Builds on OpenAI's Whisper by applying Dynamic Time Warping to cross-attention weights for precise word-level timestamp alignment without additional inference steps. Includes optional Voice Activity Detection preprocessing to reduce hallucinations and provides per-word confidence scores alongside segment-level predictions. Designed as a drop-in extension compatible with any Whisper version, with memory-efficient processing for long audio files.
