Speaker diarization

Speaker diarization groups parts of a recording by inferred speaker identity or speaker change.

Updated 2026-10-29 · Topicut editorial

Meaning

Speaker diarization groups parts of a recording by inferred speaker identity or speaker change.

A practical example

An interview system may label alternating segments Speaker A and Speaker B before an editor adds verified names.

What to check

A cluster label is not a person's identity. Review overlapping speech, short interruptions and mistaken merges before assigning real names.
