Decision points
What to consider for TTS Engine
Audience
Identify who will listen to TTS Engine and in what environment. Review TTS Engine on the actual playback device and connection profile instead of relying only on a studio headset. Use one approved TTS Engine asset as the reference, then compare every candidate output against the same listening notes.
Content
Choose text that exposes names, numbers, pacing, and difficult transitions. Use a compact TTS Engine scorecard with intelligibility, pronunciation, pacing, fit, and correction effort rated independently. Record the script revision, voice, model, reviewer, and decision so the TTS Engine result can be reproduced after a later change.
Delivery
Check output format, device playback, correction, and publishing workflow. Review the TTS Engine workflow after the first production corrections and turn repeated issues into preparation rules or tests. Use production observations to refine the next TTS Engine pilot, while keeping the original reference output available for comparison.
