Generated speech review: check the actual voice asset

Operational case

The Orin Dial guide passes a text comparison, but the renderer clips the first consonant in 'thirteen' and holds a pause through the phrase 'does not measure time.' The audio is misleading despite a correct transcript. A second candidate sounds like a named public figure because the brief said 'use their voice'; the museum has no approved voice asset for that person. The editor rejects it and selects the project's licensed neutral voice. The release packet stores the chosen asset hash, script version, pronunciation guide, transcript, listening notes, and reviewer's decision. A fresh render gets a fresh check.

Gate A: approved script vs rendered speech.
Gate B: listen to first/last words, numbers, names, pauses, level.
Gate C: voice asset approved for this project.
Gate D: transcript matches released audio hash.

Performance and operating cost

Listening to R renders of duration D costs O(RD) review time, while text checks can be automated but cannot hear clipping or unpleasant pacing. Limit candidate renders with a clear brief and revise only a failing segment when the renderer supports it, then review the assembled result. Store media hashes so captions and transcripts are tied to the file actually released. A rights or permission check is a project record, not a model confidence score. If a voice choice cannot be verified, use an approved alternative rather than describing an unverified imitation as safe.

Common Mistakes

• Do not substitute a prompt instruction for voice-asset approval.
• Do not accept audio solely because automatic transcription matches the script.
• Do not reuse an old transcript after regenerating the audio.
