Google has rolled out two new text-to-speech models, Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS, with tools for creating and controlling custom voices. The models can generate new voices from text prompts, replicate voices from 30-second samples and produce dialogue with different tones, pacing and performance cues. Google is also adding support for multi-speaker conversations, long-form audio and more than 100 languages and dialects. The two models are now available across several Google products and developer tools.
