Speaker Diarisation

Definition

Dividing speech audio into segments attributed to different speakers.

How it works

Diarisation answers who spoke when, but it does not establish the real-world identity of each speaker. Analytical models can structure call data and reveal patterns, but results depend on recording quality, language, context and the model configuration.

Business example

Speech analytics separates customer and agent turns to review the conversation structure.

What to consider

Validate outputs against real examples and involve human reviewers for consequential decisions. Apply appropriate privacy controls to recordings and transcripts.
