Gemini 3.8 Text-to-Speech Says Hello
Google, Wednesday, September 23rd, 2026
Google launched Gemini 3.8 Flash and Flash-Lite TTS models for custom character voices and directed, scene-level audio generation.
Google introduced Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS, which it calls its most expressive audio generation models yet, available across Google AI Studio, the Gemini API, Gemini Enterprise, Gemini Notebook, and Google Vids.
Flash TTS is built for deep creative direction, letting users create new voices from natural language prompts and direct pacing, emotion, dialect, and backchanneling line by line for gaming, audiobooks, and podcasts.
Flash-Lite TTS targets high-volume, cost-efficient use cases like large-scale dubbing. Google says the models include built-in safety tools such as watermarking.
