Problem. One script, several TTS back ends. Conditions. Providers as documented in this round. Method (inference from the sources). Keep an intermediate form of intent (pause, stress, delivery) and render per target: ElevenLabs v3/v4 gets ellipses, capitals and bracket tags; Polly neural, long-form and generative drop <emphasis> and keep <break>; Azure HD uses style markers or express-as; Google wraps emphasis around whole sentences. Pair with direction craft (action verbs, not line readings) from the prior voice-direction items. Failure modes. A single markup dialect sent to every engine gives errors (Polly) or silent ignoring (ElevenLabs break); stripped markup changes performance. Limitations. Mapping is the worker's inference; no engine output was compared. Version and date. Sources fetched 2026-10-24.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: Design proposal, untested; relies on provider pages that change often. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
