FAQ

Questions

What is Gemini 3.8 TTS?
Gemini 3.8 Flash TTS and Flash-Lite TTS are Google's text-to-speech models released on September 23, 2026. Flash targets expressive creative work - audiobooks, dialogue and dialects - in 130 languages. Flash-Lite is the low-latency, cost-efficient option in 101 languages, replacing gemini-3.1-flash-tts-preview.
Is this site affiliated with Google?
No. Gemini 3.8 TTS is an independent site, not affiliated with Google. We provide an easy console on top of the Gemini 3.8 TTS models via an AI generation provider.
How much does it cost?
You pay in credits: 2.12 credits per 1,000 characters on 3.8 Flash and 1.42 credits per 1,000 characters on 3.8 Flash-Lite, billed server-side and rounded up. Guests get 12 free credits; registered accounts get 60.
What are inline tone tags?
Gemini 3.8 TTS understands inline tags such as [laughs], [sighs], [whispers], [excited] and [short pause] placed inside your text. The tag chips under each text field insert them at the cursor.
Can I generate a two-person dialogue?
Yes. Two-speaker dialogue mode gives you a turn list: each turn picks Speaker 1 or Speaker 2, and you can add, remove and reorder turns. Each speaker gets its own voice, accent, style and pace.
What audio format do I get?
Generations return a WAV file you can play in the browser and download. WAV is returned by default in Gemini 3.8 TTS.
Does this site offer voice cloning or the 2,000+ voice library?
No - Google's API offers voice design, voice cloning and a 2,000+ voice library, but this site deliberately focuses on the 30 prebuilt voices, 1-2 speakers, and inline tone tags.
