Live TTS Model Family Options for Voice Agents
*Category:* Enhancement
*Location:* Voice Agents → Create or Edit Voice Agent → TTS Model Family
*Release Date:* September 1 2026
What’s new
The TTS Model Family picker now uses the live supported catalog, including availability, recommendation, and deprecation labels.
New Voice Agents default to Flash; Turbo remains available and is clearly marked Deprecated.
Voice Style controls appear from each family’s actual capabilities rather than a fixed model-name rule.
Existing legacy selections remain visible, and unrelated edits no longer silently change the saved TTS model.
Safe cached and fallback catalogs keep the form usable during temporary catalog failures.
How to use it
Open a Voice Agent and use the *TTS Model Family* picker.
Choose Flash for new agents, or keep an existing family if you are not changing speech settings.
Impact
Voice Agent speech-model choices stay current while preserving existing configurations and exposing the right controls for each family.
