About Gemini 3.8 Flash TTS
Gemini 3.8 Flash TTS is Google's newer-generation text-to-speech model, built for studio-grade voice fidelity, expressive acting, and long-form stability. 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, expressive delivery at speed. For even lower latency and cost on high-volume workloads, see [Gemini 3.8 Flash Lite TTS](/playground/gemini-3-8-flash-lite-tts); for premium studio-quality output, see [Gemini 2.5 Pro TTS](/playground/gemini-2-5-pro-tts).
