About Gemini 3.8 Flash TTS
What it does
Gemini 3.8 Flash TTS is Google's flagship text-to-speech model. In Audio Generator it reads your text in one of 30 Gemini voices and returns an MP3. It speaks more than 130 languages, detected from your text, and follows a short delivery direction plus sounds you place in the text, such as <laugh>, <sigh>, or <short pause>.
When to use it
- Narration, audiobooks, and explainers that need a studio-quality voice and natural pacing.
- Scripts in less common languages and regional dialects.
- Lines with laughter, sighs, breaths, or pauses at exact points.
What to know before you run it
Gemini reads your text exactly as written, so put directions in the voice instructions, not in the text. With Enhance prompt on, Pipe2 turns your instructions into a short style, adds sound tags without changing your words, and can pick a voice for you. Text can be up to 5,000 characters. You pay for the audio Google actually produces, so the price follows the length and pace of the speech. With Enhance prompt on, the price also includes that enhancement step. Multi-speaker dialogue and custom voices are not available here.
