📄 Description

Description

Fixed incorrect locale extraction in Azure TTS SSML generation. split("-")[:1] only takes the first segment (e.g., "en" from "en-US"), producing an invalid SSML xml:lang attribute. Changed to [:2] to preserve the full locale (e.g., "en-US").

Fixed

Azure TTS now correctly uses the full locale (e.g., "en-US") in SSML xml:lang attribute instead of just the language code (e.g., "en")

Additional Information

The other TTS code paths in the same file already use the full locale correctly
Tested by reviewing the code path and verifying the SSML output format matches Azure documentation requirements
Self-reviewed the code changes
Rebased onto dev (replaces #22432)
