# Can speech-pattern changes prove that a candidate used AI?

No. A later speech-pattern change can only be a source-review prompt when the interview includes a usable open-ended baseline and preserves the recording context. It is not proof of AI use, deception, or ineligibility. A reviewer must inspect context, exclude protected traits, and keep missing or unusable evidence from becoming a negative conclusion.

## The full answer

Pauses, accent, slower speech, disfluency, disability, code-switching, translation, stress, or polished delivery can have many explanations. A reviewer must inspect the source and use contextual follow-up.

## What to verify

A reviewer must inspect context, exclude protected traits, and keep missing or unusable evidence from becoming a negative conclusion.

A qualified person reviews the evidence and remains responsible for the final employment decision.
