About Gemini 3.1 Flash TTS
Gemini 3.1 Flash TTS is Google's fast, cost-efficient text-to-speech model for expressive multi-speaker audio. Define any number of speakers, each with a distinct voice, accent, emotional style, and pace, then script a conversation across ordered dialogue turns with inline tone tags like [whispers] or [shouting]. It is ideal for character dialogue, game and video voiceovers, podcasts, and narration where you need natural delivery at speed and scale. For the highest-fidelity studio output, see [Gemini 2.5 Pro TTS](/playground/gemini-2-5-pro-tts).
