AI-103: Developing AI Apps and Agents on Azure

The SSML phoneme element allows you to specify the exact pronunciation of a word using a phonetic alphabet such as IPA or SAPI. This directly addresses mispronunciation of specific technical terms with minimal effort, since you only need to annotate the problematic words in the SSML markup rather than retrain a model. In contrast, say-as is meant for interpreting content types (like dates or numbers) rather than correcting phonetic pronunciation, prosody adjusts pitch/rate/volume rather than pronunciation, custom neural voice training requires substantial data collection and model training effort, and Whisper is a speech-to-text model, not applicable to a text-to-speech pronunciation issue.
