Google adds a talking avatar to Gemini 3.8 Live for business

Google has put a face on its real-time voice model. Gemini 3.8 Live with Live Avatar, which Google says is available now in Gemini Enterprise, pairs the live dialogue model it launched last week with streamed, lip-synced video of an animated character, so a company’s support or onboarding agent can listen, watch and answer on camera instead of in a text box or on a phone line, according to a Google blog post on Sep 24.

What it does, according to Google:

• Voice plus video in one loop. The avatar takes in what it sees and hears and answers with speech, facial expressions and lip movement. Google describes the turn-taking as fluid and the video as “near real-time.”
• Works while it talks. Asynchronous tool calls let the agent fetch data or run a task in the background without pausing the conversation. Google’s demo shows it checking a guest into a hotel.
• 97 languages. Google says the avatar can switch languages mid-conversation and that lip-sync and expressions keep up “without degrading video fidelity or introducing visual drift.”
• Brand avatars. Companies get a library of preset characters, each with its own look and voice. Building a custom avatar from a single reference image is limited to enterprise customers on an allowlist for now, Google’s Sep 24 post says.
• Watermarked. Google’s Sep 24 post says all audio and video output carries its SynthID watermark, an invisible marker meant to keep AI-generated content detectable.

What it cannot do (yet): The post describes no version in the consumer Gemini app. Custom likeness is gated behind the allowlist. Google’s Cloud announcement says the feature is generally available with U.S. and EU endpoints.

Who for: Businesses on Gemini Enterprise that run customer service, kiosks, check-in desks or product walkthroughs and want a face on the agent.

Replaces: A text chat widget or a voice-only phone bot for front-desk and help-desk work.

Risks: A lifelike talking face raises the stakes when the agent is wrong. Avatars built from a reference image invite likeness misuse, which is the reason Google gives for gating them. The quality claims across 97 languages are Google’s own and have not been tested independently. SynthID only helps if someone runs a detector.
