Decision points
What to consider for TTS Engines
Audience
Identify who will listen to TTS Engines and in what environment. Include the most consequential failure case in the TTS Engines pilot rather than postponing it until after automation. Test TTS Engines with both a typical passage and a deliberately difficult passage so an easy success does not hide edge cases.
Content
Choose text that exposes names, numbers, pacing, and difficult transitions. Compare the TTS Engines candidates without provider labels where practical, then reveal operational and price differences afterward.

Re-run the TTS Engines reference whenever the source script, voice, model, plan, endpoint, or target playback environment changes.
