Director, Research Science, on Behalf of the Gemini Audio Team Google just launched new AI tools that let you create and customize realistic voices from scratch. You can direct these voices to sound exactly how you want, from their accent to their emotional tone. It’s perfect for making audiobooks, games, or podcasts that sound like real people talking. Plus, they added safety features to make sure these voices are used responsibly. Today, we’re introducing two new text-to-speech models to the Gemini family, transforming voice generation from static presets into a dynamic creative studio. These models enable creators, developers, and enterprises to create richer, more expressive audio experiences, while enabling improved user experiences in products like Gemini Notebook and Google Vids. These models complement our fast-growing Gemini Audio family, following 3.5 Live Translate, 3.5 Transcribe, 3.8 Live, and 3.8 Live Extended Thinking.
