Earlier this week, we introduced greater control over audio generation with an upgrade to our Gemini 2.5 Pro and Flash Text-to-Speech models.

But generating expressive speech is only one side of the conversation. Today, we’re releasing an updated Gemini 2.5 Flash Native Audio for live voice agents. This update improves the model’s ability to handle complex workflows, navigate user instructions, and hold natural conversations.

Gemini 2.5 Flash Native Audio is now available across Google products including Google AI Studio, Vertex AI, and has also started rolling out in Gemini Live and Search Live, bringing the naturalness of native audio to Search Live for the first time. This means you can more effectively brainstorm live with Gemini, get real-time help in Search Live, or build the next generation of enterprise-ready customer service agents.

Beyond powering helpful agents, native audio unlocks new possibilities for global communication. We’re introducing live speech translation, a capability that enables streaming speech-to-speech translation for headphones. It preserves the speaker’s intonation, pacing and pitch. This beta experience is rolling out in the Google Translate app starting today.

To enable the breadth of use cases across surfaces and products, we have improved Gemini 2.5 Native Audio in three key areas:
