Gemini 3.1 Flash TTS: Common Questions
Answers to the questions people ask most about this Google text-to-speech model and its expressive voice features.
What exactly is Gemini 3.1 Flash TTS?
It is a Google text-to-speech model that turns written scripts into natural, high-fidelity audio, with detailed control over tone, emotion, rhythm, and speaking style.
How do audio tags work?
They are short cues such as [whispers], [shouting], or [urgency] typed directly into your script. The model treats them as directions and shifts delivery at that precise point — over 200 are available.
Which languages are supported?
More than 70. That range makes it a practical choice for audiobooks, voice assistants, and marketing content aimed at audiences in different regions.
Can it voice more than one speaker?
Yes. A single generation can contain several speakers, each with its own voice profile, pace, accent, and style, so dialogue stays clear and distinct.
How can I steer the delivery?
Write a plain-language brief covering character, mood, accent, and tone, then add inline audio tags wherever you want moment-to-moment changes.
Can I use the audio commercially?
Yes. Output is cleared for commercial work, from audiobooks and interactive agents to multilingual and enterprise audio needs.
