Gemini 3.8 Flash and Flash-Lite text-to-speech models are available in the Gemini API

Google for Developers has introduced two Gemini 3.8 text-to-speech models, available now through the Gemini API in Google AI Studio.

Gemini 3.8 Flash TTS is designed for creative work. It lets developers use natural language to create custom vocal personas and to direct cues, pacing, and dialects for immersive apps and narrative games. Gemini 3.8 Flash-Lite TTS is built for high-volume audio pipelines, including bulk audiobook production and audio dubbing.

Further details are in Google’s Gemini 3.8 text-to-speech announcement.
