What it measures
A single audit record typically contains one prompt and response pair. The field is part of the record for interactions with Microsoft's own Copilot applications.
What it does not show
A dictated prompt sent to Copilot is a prompt in this sense, so it can appear in the record. The page does not say whether the records include raw audio, and it does not say which roles can read them.
