I was wondering if anybody knows open source projects that implement transcription to provide a grep-like functionality for mp3 files?<p>Of course I could write it myself, but I'd rather not want to re-invent the wheel here.
Right now, the best I know of would be to get a transcript with whisper, and grep that. Do you know of better ways? Searching for a waveform for certain words is not quite something that anyone's done yet, to my knowledge.
