Gemini 3.8 text-to-speech says hello

Google has launched two new text-to-speech models, Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS, that enable users to create highly customizable and expressive AI-generated voices with granular control over emotion, pacing, and dialect. These models are available across Google AI Studio, Gemini API, and other platforms, supporting applications like audiobooks, podcasts, video content, and voice agents while incorporating safety features like watermarking. The technology allows creators to generate entirely new character voices from scratch using natural language prompts or replicate existing voices with detailed line-by-line direction.
