Questions About Gemini 3.1 Flash TTS, Answered
Straight answers on how Gemini 3.1 Flash TTS handles audio tags, languages, multi-speaker dialogue, and commercial use.
So, what does Gemini 3.1 Flash TTS actually do?
It's Google's text-to-speech model that turns written copy into clean, natural audio, and it takes direction on tone, tempo, and delivery instead of reading flatly.
How do the inline audio tags work?
Tags are short bracketed cues such as [whisper] or [urgent] typed inside the script. The engine performs them at that exact point, so you steer delivery without a separate settings panel.
Which languages can I publish in?
More than 70. That covers audiobooks, localized ads, and voice assistants across most major markets, all generated from one script.
Can one generation include several speakers?
Yes. Assign each role its own voice, accent, and tempo, and the model keeps them distinct throughout a single dialogue track.
What's the best way to steer the performance?
Start with a short written brief describing the character and scene, then layer inline tags wherever the mood, pace, or volume should shift.
Can I use the output commercially?
Yes — narration, ads, audiobooks, and in-app assistants are all fair game, with no studio session or extra licensing required.
