Transcription
Transcription turns recorded speech into text, so a recording can be searched, quoted and cited like any other document.
Voice notes, call recordings and hearing audio carry evidence that never reaches the written file otherwise.
For evidential use the transcript has to keep timestamps, so a quotation can be checked against the recording at the point it was said.
