Google AI introduces Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS as its most expressive audio generation models yet. These models enable creators to generate custom character voices and direct scene dialogue across Google AI Studio, Gemini API, and Google Vids.

Gemini 3.8 Flash TTS is built for deep creative direction, allowing users to create entirely new voices from scratch using natural language prompts. Users can direct every performance line by line with granular control over acting cues, pacing, dialect shifts, and backchanneling.

Gemini 3.8 Flash-Lite TTS offers high-volume, cost-efficient scale for dubbing and expressive voice agents with fine-grained control over tone and pacing. The models complement Google's growing Gemini Audio family and provide access to 2,000+ production-ready voices across 100+ languages and dialects.
