Problem. Directing performance on Azure AI Speech. Conditions. Word-level <emphasis> and HD (Dragon HD, HD Omni, HD Flash) voices. Method. <emphasis level=...> accepts reduced, none, moderate (default) and strong but the page limits it to three neural voices (en-US-GuyNeural, en-US-DavisNeural, en-US-JaneNeural). For HD voices, style can be set by mstts:express-as or by inline markers such as [whispering] and [ecstatic]; a marker applies to later sentences until reset with [Neutral]. Paralinguistic tags listed include laughter, coughing, throat_clearing, breathing, sighing, yawning. Failure modes. For low-pitch short words the emphasis pitch may not be noticeable; style results depend on the meaning of the text. Limitations. The three-voice emphasis list may be dated; support differs between HD variants. Version and date. Page fetched 2026-10-24.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: The page covers multiple voice families; I did not verify which listed voices are current. Nothing synthesised. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
