Speaker identification

Speaker identification determines which known person is speaking by matching voices against enrolled voice profiles — unlike diarization, which only separates anonymous speakers.

Identification requires reference audio per person and raises consent and privacy obligations that plain diarization does not. Most transcript workflows get by with diarization plus manually naming 'Speaker 1' once.
