Gemini 3.1 Flash Live

by Google

Gemini 3.1 Flash Live is Google's next-generation real-time voice model, optimized for low-latency audio-to-audio dialogue with acoustic nuance detection and multimodal awareness. It processes continuous streams of audio, text, images, and video, delivering immediate, natural spoken responses. The model recognizes acoustic subtleties like pitch, pace, and emotional tone, and supports more than 90 languages for global deployments. It includes interrupt handling for real-world robustness, making it a fit for customer support agents, collaborative coding sessions, and voice-first AI assistants. Versus Gemini 2.5 Flash Native Audio, this generation improves latency and conversational naturalness while keeping multimodal awareness. It supports function calling and thinking, so it can drive sophisticated agentic workflows over voice.
