What happened
- On September 24, Google introduced Gemini 3.8 Live with Live Avatar, a real-time voice model that generates an animated face synchronized with what it says. It became generally available in Gemini Enterprise, with servers in the United States and the European Union.
- The system understands and speaks 97 languages, detects a change of language mid-conversation and can query internal systems while it keeps talking.
- Google offers a library of predesigned avatars. Custom avatars, created from a reference image, are available only to authorized companies after a verification process.
- All audio and video carry SynthID, an imperceptible Google watermark. Among the first users, the company names Cox Automotive, Salesforce and Equal AI, which handles more than a million calls a day in nine languages in India.
Why it matters
- The stated use is customer service. For banks, insurers and retailers in Chile, that means the next person answering a video call may be a generated face, with the voice and tone the brand chooses.
- The watermark is imperceptible by design: it protects Google and whoever has the detection tool, not the person in the conversation. If nobody says the face is synthetic, transparency stays in the file, not in the conversation.
- The servers are only in the United States and Europe. A Chilean company that uses it to serve its users will be sending third parties’ voice and image out of the country, a point the new personal data law requires companies to look at.
The number
97 languages. That’s the reach of the lip and voice synchronization Google claims for the model.
Context
Real-time voice is already being billed by the minute, as GPT-Live-1 at $0.05 per minute of voice showed. And labeling synthetic content remains the rule Europe kept in place when it postponed the rest of its AI law.
What’s next
- The version with extended reasoning, Gemini 3.8 Live Extended Thinking, remains in private preview.
- No date for servers outside the United States and Europe.
- No timelines announced for opening custom avatars without verification.
Bottom line
Watermarks work in only one direction, as Anthropic’s checker, which confirms its own mark but doesn’t prove the opposite, showed. SynthID serves to prove a video was made by Google, not to let someone know they’re not talking to a person.
