Gemini 3.1 Flash TTS

Google released Gemini 3.1 Flash TTS, a new text-to-speech model that generates audio from text using prompts sent through the standard Gemini API. Unlike typical AI models, this one accepts detailed creative instructions (called prompts) to control how the audio sounds, including vocal style, pace, accent, and emotional tone, allowing users to create speech with specific characteristics like a particular regional accent or energetic delivery.
