A developer has improved their open-source tool, crv, by addressing issues with Large Language Models (LLMs) misinterpreting audio and video content. The tool now uses a voice-activity detection (VAD) gate with Whisper to prevent hallucinated captions from music-only audio. Additionally, crv incorporates optical character recognition (OCR) to read burned-in captions in videos, using this on-screen text as ground truth to correct potential misinterpretations from the audio transcription, especially for names, numbers, and specific terms.
