Google releases Gemini 3.8 Flash TTS and Flash-Lite TTS text-to-speech models

Google announced two new Gemini 3.8 text-to-speech models, positioned as its most expressive yet.

Gemini 3.8 Flash TTS targets creative work, letting developers use natural language to define vocal personas, cues, pacing, and dialects, while Gemini 3.8 Flash-Lite TTS is built for high-volume pipelines such as bulk audiobook production and audio dubbing.

Both are available now through the Gemini API in Google AI Studio.
