Description

Gemini 3.8 Flash TTS is a generative text-to-speech model from Google designed for expressive voice creation, character design, dialogue direction, and multilingual audio production. Instead of limiting users to fixed voice presets, the model can create entirely new vocal identities from natural-language descriptions. Developers and creators can specify attributes such as accent, role, timbre, speaking style, pacing, and other voice characteristics across more than 100 languages and dialects. The model also offers access to more than 2,000 production-ready voices and supports voice replication from a short authorized audio sample. Performance controls allow users to direct individual lines with stage directions, pacing instructions, dialect shifts, emotional cues, and conversational backchanneling. Gemini 3.8 Flash TTS supports long-form generation while maintaining voice consistency, making it suitable for podcasts, audiobooks, localization, and other extended audio projects. Native two-speaker scene support lets users create multi-turn conversations from a single script while preserving distinct voices and natural turn-taking. Google includes consent verification, SynthID watermarking, and C2PA credentials to provide greater transparency and safeguards around generated and replicated voices. Gemini 3.8 Flash TTS can be used through Google AI Studio and the Gemini API and is intended for developers, creators, enterprises, media companies, and teams building expressive speech experiences.

Description

The Gemini Live API is an advanced preview feature designed to facilitate low-latency, bidirectional interactions through voice and video with the Gemini system. This innovation allows users to engage in conversations that feel natural and human-like, while also enabling them to interrupt the model's responses via voice commands. In addition to handling text inputs, the model is capable of processing audio and video, yielding both text and audio outputs. Recent enhancements include the introduction of two new voice options and support for 30 additional languages, along with the ability to configure the output language as needed. Furthermore, users can adjust image resolution settings (66/256 tokens), decide on turn coverage (whether to send all inputs continuously or only during user speech), and customize interruption preferences. Additional features encompass voice activity detection, new client events for signaling the end of a turn, token count tracking, and a client event for marking the end of the stream. The system also supports text streaming, along with configurable session resumption that retains session data on the server for up to 24 hours, and the capability for extended sessions utilizing a sliding context window for better conversation continuity. Overall, Gemini Live API enhances interaction quality, making it more versatile and user-friendly.
