Short-Clip Speech Extraction and Audio Enhancement for Live Photos
Pain Points (Public)
Users capturing incidental conversations or voice notes via smartphone Live Photos struggle to demux the bundled audio track, and the resulting 2–3 second micro-clips are often corrupted by environmental noise, low gain, or muffled speech, preventing reliable automated transcription.
Suggested Approach (Public)
Extract the paired audio stream from Live Photo containers (such as MOV/HEIC pairs) using FFmpeg, apply spectral denoising and neural vocal enhancement (via tools like iZotope RX or DeepFilterNet) to amplify faint speech, and output a clean master ready for high-accuracy Whisper transcription.
