What is Gemini 3.8 Flash TTS?

Gemini 3.8 Flash TTS is Google’s advanced text-to-speech model for generating expressive, customizable, and multilingual synthetic speech. The model is designed for creative voice direction, allowing users to generate original characters and vocal personas using natural-language instructions instead of relying only on preset voices. Voice characteristics can be customized by role, accent, timbre, pacing, delivery style, and other attributes across more than 100 languages and dialects. Google also provides a library of more than 2,000 production-ready voices for projects that do not require a newly generated vocal identity. Voice replication can recreate a consistent vocal profile from a short reference sample when the user has permission to use the voice, with built-in consent verification requirements. Creators can direct performances line by line with stage directions and cues for emotion, timing, whispers, pauses, laughs, sighs, gasps, and conversational reactions. Long-form generation is designed to preserve voice quality, pacing, and character identity across extended content such as audiobooks, podcasts, and narrated media. Native two-speaker scene staging allows a single script to produce natural multi-turn dialogue with distinct speakers and controlled conversational timing. These capabilities make Gemini 3.8 Flash TTS applicable to gaming, interactive characters, voice agents, media localization, dubbing, branded voices, podcasts, audiobooks, and other audio-production workflows. Google applies SynthID watermarking to generated audio and supports C2PA credentials and consent checks to improve transparency and protect voice owners. Gemini 3.8 Flash TTS is available through Google AI Studio and the Gemini API, with additional integrations and deployments across Google products, enterprise applications, and third-party developer platforms.
