Summary

Melvin Vivas says he used Google's live translation to follow a wedding ceremony in Switzerland. He quotes Google's announcement that Gemini 3.5 Live Translate is now in the Gemini Live API. The demo video shows a speaker sending one microphone stream to listeners, who each hear it in their own language. The model notices when the speaker changes language, with no setup needed. The model works with more than 70 languages and is available in the Gemini API and Google AI Studio.

Key points

• Gemini 3.5 Live Translate is available through the Gemini Live API and supports more than 70 languages.
• Demo flow: the speaker starts a session and captures microphone audio. Attendees get a URL or QR code, join on their phones and pick a listening language.
• Each time a listener picks a new language, the app starts a new Live API session. Every translation uses the same microphone audio.
• Several target languages run at once in the demo, including Japanese, Spanish, Tamil and Mandarin.
• The model notices language switches by itself (for example English to German, or Sinhala to English) with no configuration.
• Some translations in the machine transcript are garbled or repeated, so test quality for your language pairs before relying on it.
• The creator used it in real life to follow a live wedding ceremony in Switzerland.
