Gemini 3.1 Flash TTS converts written text into natural-sounding speech in seconds. If you have ever had to record a voiceover, hire a narrator, or sit through robotic text-to-speech output, this is the direct fix. You type the text, pick a voice, and get back a clean audio file ready for any project. The model ships with 30 distinct voices, from warm and conversational to formal and precise. A style prompt written in plain language, such as "speak slowly with confidence" or "use a calm, friendly tone," shapes the pace and emotion of the output. Expressive markup tags let you mark specific phrases as [whispering] or [laughing] so the delivery matches the script exactly. Multilingual support spans more than 70 language codes. Whether you are producing a podcast intro, a product demo narration, or a foreign-language audio track from an existing script, Gemini 3.1 Flash TTS fits directly into that step. Paste your text, dial in the voice and tone, and download the result.

On Picasso IA, the whole process runs in your browser. Paste your text, pick a voice, write a brief style note, and your audio file is ready.
