Gemini 3.1 Flash TTS: Frequently Asked Questions
Answers to the questions people ask most about this Google speech model and how it handles expressive narration.
What exactly is Gemini 3.1 Flash TTS?
It is Google's expressive speech model. Feed it written text and it returns natural, high-fidelity audio, with detailed control over tone, emotion, rhythm, and delivery style.
How do audio tags work?
They are short inline markers — [whispers], [shouting], [urgency] — placed inside the script. Each one tells the voice how to perform that specific moment.
Which languages can it speak?
More than 70. That range makes it practical for global audiobooks, multilingual assistants, and campaigns that need to run in several markets at once.
Can one clip include several speakers?
Yes. You can script a full conversation, and each speaker keeps their own voice profile, style, pace, and accent inside a single generation.
How can I direct the performance?
Two ways: describe the character, mood, and accent in plain language, then fine-tune specific moments with inline audio tags.
Can I use the audio commercially?
Yes. Output is cleared for commercial use, from audiobooks and interactive agents to multilingual content and enterprise voice work.
