Gemini 3.1 Flash TTS: Questions Answered
Quick answers about how this Google speech model works, what it can produce, and where you are allowed to use it.
What exactly is Gemini 3.1 Flash TTS?
It is Google's expressive speech model that reads written text aloud as natural, high-fidelity audio, with detailed control over tone, emotion, rhythm, and speaking style.
How do audio tags work?
You place short cues such as [whispers], [shouting], or [urgency] directly in the script, and the voice shifts its expression at that exact moment. More than 200 cues are available.
Which languages are supported?
More than 70 languages are covered, which makes it a practical fit for global audiobooks, voice assistants, and localized content production.
Can several speakers appear in one clip?
Yes. Each speaker keeps an independent voice profile, style, pace, and accent inside a single generation, so full dialogue scenes work out of the box.
How can I steer the delivery?
Write a plain-language description of the character, mood, accent, and tone, then add inline audio tags for moment-by-moment adjustments.
Can I use the audio commercially?
Yes — the output is ready for commercial work, including audiobooks, interactive agents, multilingual content, and enterprise voice needs.
