Summary
Google began rolling out Gemini 3.8 Live and 3.8 Live Extended Thinking to developers, enterprises and users, positioning them as near-real-time voice AI models for more natural, production-ready agents.
97 languages can be detected and switched between mid-conversation, while the models handle visual input in near real time and keep talking as they execute tools and API calls in the background.
82.6 on Artificial Analysis' Speech to Speech Quality Index put Extended Thinking in the top overall spot; it also scored 68.6% on τ-Voice, 35.1% on Sierra's banking benchmark and 97.7% on Big Bench Audio.
Google said 3.8 Live is built for scale and cost efficiency, while Extended Thinking targets higher-complexity workflows in Search, Workspace and enterprise deployments including Docs, Gmail and Keep.
SynthID watermarking is being applied to all audio generated by Google's AI products, adding a detectability layer as the company expands voice features through its API, app and enterprise stack.
