Audio Transcription

Speech-to-text on an audio clip. The simplest labeling primitive in the audio family: input is raw audio, output is a typed transcript.

Files

• basic.py — flat transcript string.
• with_diarization.py — segments labeled with a speaker identifier.
• with_timestamps.py — segments with start/end timing in seconds.

When to use

• Building a training set for ASR fine-tuning.
• Pre-filling a CRM with call transcripts before human cleanup.
• Generating searchable text for an audio archive.

For typed call/meeting fields rather than a raw transcript, see _12_audio_extraction/.
