Speaker Diarization: How to Review Who Said What

Understand speaker labels, check attribution and correct names in a multi-speaker transcript.

What speaker diarization means

Speaker diarization separates speech into segments associated with different speakers. A label such as Speaker 1 groups passages the system attributes to the same voice. The label alone does not establish the person’s identity.

ScreenApp’s transcript can display speaker labels. Use the recording to check those labels before naming people or quoting them.

Review a conversation

  1. Open the transcript beside the recording.
  2. Listen at a clear speaker change.
  3. Check which label is attached to each passage.
  4. Rename a label when you can establish the speaker’s identity.
  5. Check other passages assigned to that label, especially overlaps and brief interjections.

Follow speaker-label editing for the current controls. Renaming a label does not automatically correct every underlying attribution error.

Handle uncertainty

Two voices may be grouped together, or one person’s speech may receive more than one label. Overlapping speech, quiet voices and poor audio make review harder. Keep uncertain attribution explicit rather than assigning a name to make the transcript look finished.

If words are wrong, use transcript editing. If attribution remains mixed, preserve the original and send example timestamps to support.

Improve the next recording

Make a test recording with the actual microphones and participants. Check that all voices are audible, and reduce avoidable interruptions or cross-talk. A speaker introducing themselves can provide context for the human review, but it is not a guarantee of automatic identification.

The app’s People settings support speaker names used by identification. Only use names you can verify from the source and the people involved.

Export after checking

Download a new transcript after corrections so your local copy includes the changes. Read summaries and generated notes separately, since an attribution error can affect who appears responsible for an action.
