Google's new Flash TTS models let you design AI voices from scratch using text descriptions

Google has announced the launch of two new text-to-speech models, Gemini 3.8 Flash TTS and Flash-Lite TTS, supporting over 100 languages. The Flash TTS model can create new voices from text descriptions, while both models allow users to add stage directions to individual lines and generate two-voice dialogue from a single script. A voice cloning feature enables users to build a voice profile from a 30-second sample, enhancing the customization of voices. These advancements represent a significant step towards improving user experience in audio content creation.
