Speaker Diarization

The task of determining who spoke when over the timeline of an audio recording.

Speaker diarization is a core requirement in multi-speaker environments such as meetings, panels, call-center recordings, and court audio. The system segments the audio and groups similar voice segments under the same speaker identity. This goes beyond transcription by helping interpret the structure and interaction within speech. It is a foundational component for meeting intelligence and enterprise audio analytics.
