About
whisper-timestamped is an open-source extension of OpenAI's Whisper model, offering multilingual automatic speech recognition with enhanced word-level timestamps and confidence scores. Unlike the original Whisper, it provides more accurate start/end estimations for words and assigns confidence scores to each word and segment. The tool utilizes Dynamic Time Warping (DTW) applied to cross-attention weights for precise alignment, and it's designed to be memory-efficient, capable of processing long audio files. It also integrates Voice Activity Detection (VAD) to prevent hallucinations from silent audio and supports fine-tuned Whisper models from Hugging Face. This makes it ideal for developers and researchers requiring highly accurate and detailed audio transcription.
