In order to measure the impact of chunking, we picked a random 10% subset of the [earnings22](https://huggingface.co/datasets/argmaxinc/earnings22-12hours) dataset which comprises corporate earnings call recordings in English with various accents. The long-form nature (>1hr/clip) and the density of speech in these audio clips are intended to stress test VAD accuracy. If VAD is inaccurate, WhisperKit will present speech segments to the Whisper model that start middle-of-speech and cause Whisper to hallucinate at increased rates. ## Dataset: `earnings22-12hours` Long-Form Audio (>1hr/clip) - ~12 hours of earnings call recordings in English with various accents ### with VAD | | WER (↓) | QoI (↑) | File Size (MB) | Code Commit |
