A meeting assistant labels speakers numerically. A later summary assigns a commitment to a named colleague even though the connection between voice and identity was never confirmed.
Separate diarisation from identification
Google’s speaker-diarisation documentation describes detecting speaker changes and labelling voices by number. That process does not automatically verify a person’s identity.
An illustrative project call may include several participants sharing a room or device. A numbered voice segment should not become an authoritative attribution simply because the calendar contains a list of invitees.
Mark unconfirmed mappings and allow an authorised reviewer to correct them.
Test the situations that break attribution
Include overlapping speech, brief interjections and changes in audio conditions where those occur in the intended workflow. Evaluate the assignment of material statements, not only whether the transcript contains the words.
A mistaken speaker label can become consequential when the application creates a task, records approval or summarises a disagreement. Require the appropriate confirmation before treating such an output as a commitment.
Do not use uncertain diarisation for decisions about individual performance or conduct. The technical label is insufficient evidence for that purpose.
Keep corrections connected to outputs
If attribution changes, review the summaries and tasks derived from it. Correcting the transcript alone may leave the wrong person responsible in another system.
Keep speaker correction separate from editing the words spoken. A reviewer may establish that the transcript is accurate but attributed to the wrong participant. Both changes should propagate appropriately, especially where the application generates meeting minutes or tasks that other colleagues will treat as a record of responsibility.
A useful assistant helps preserve who said what while making uncertainty visible. It should not turn a voice-separation feature into an identity assurance that the underlying system never supplied.
