Google launches Gemini 3.8 Flash TTS with custom voice design and 100+ languages
New text-to-speech models let users design custom character voices, direct scene dialogue, and clone voices with consent verification.
What to know
- Google released two new TTS models — Gemini 3.8 Flash TTS and Flash-Lite TTS — with custom voice design, over 100 language support, and 2,000+ ready-made voices.
- Voice replication requires verbal consent from the voice owner as a safeguard against misuse.
- The models rank #1 or #2 on several third-party benchmarks (Hume AI, Artificial Analysis) for quality and pronunciation, though they trail the fastest competing TTS models on raw generation speed.
- Availability spans Google AI Studio, the Gemini API, Gemini Enterprise, Gemini Notebook, and Google Vids.

Artificial Analysis publishes independent speed and quality benchmarks
Third-party AI benchmarking tracker Artificial Analysis reported Gemini 3.8 Flash TTS processes 44.1 characters per second (about 2.7x realtime) versus 40.2 for Flash-Lite, placing Google's models behind faster competitors like Falcon 2, while noting the Flash model debuts at #1 on its Pronunciation Robustness Benchmark and #2 on its Provider Voice Arena Leaderboard.
“Gemini 3.8 Flash TTS processes 44.1 characters per second, compared to 40.2 characters per second for Gemini 3.8 Flash-Lite TTS, approximately 2.7x and 2.4x faster than realtime, respectively.”

The new Gemini 3.8 TTS models are super-cheap and can generate conversations between multiple voices (from 2,000+, or you can clone your own) - I built a little UI for it, then had Claude knock up a script where two pelicans debate moving to Pacifica Pier

Interesting to see that they are publishing a new tts model. I remember that they refused to release one of them a few years ago because they were too afraid of abusing it. Now they just release it without any much thought lol

An education account I have lists 3.1 Pro, and 3.6 Thinking and Flash as the available models in the app.My personal account, 3.6 Flash Lite and 3.5 Thinking.Meanwhile, I can go hog wild and drain my bank account on GCP. I don’t though, because my family has to eat.

Google is spreading too thin, as gemini isn't really that intelligent.They are creating gemini SOTA (not really any more), flash versions, text-to-speech, video (omni), etc.I can see they want to create an ecosystem, but I see no focus in any one area.

Pet peeve on Google's AI rollouts: there's no alignment across the three platforms they have, consumer, prosumer, cloud. Scroll to the end of every release, including this one, and you'll see different availabilities. The fun part is the models don't even have the same capabilities across platforms! Omni Flash, last I tried and read the docs, is…

I vibe coded a playground UI for trying this out. The conversation mode is neat, and it's very expensive - most of my experiments have cost less than a cent.

My primary use case for TTS is converting written content (blogs, articles, etc.) in to clips I can listen to on the go.Is there a good browser extension that does this with a flexible TTS backend? I know Qwen, Kokoro, and VibeVoice all have decent quality..

It's giving me an error when I try to generate a voice with Voice Design in AI Studio. It also says voice replication isn't available in my region.Also weird that there are no "neutral gender" voices in the English language. There's also limited "use cases," like the "Gaming" use case is empty?And there's no pricing listed anywhere.I don't know, I…

Related, for embedding small models, this lib is incredible.Having a voice under 1Mo is crazy, even if it sounds robotic.

I direct my own extended daydream Star Trek fanfic (okay, I'm on season 2 episode 17) and recently I looked to see if I could have each scene file be read aloud a la an audiobook or radio drama.Getting GPT-Live to have unique enough voices and to be expressive with how I imagine the voices going in my head is hard to direct, there's not enough…

> Voice replication: Recreate consistent vocal profiles from just a 30-second audio sample of your voice or a voice you have the rights to use, backed by built-in consent verification, SynthID watermarking, and C2PA credentials to protect both developers and their vocal talent.I guess voice cloning is widely enough available now from other…
-
Forget the leaderboard wins. The real headline in Google's Gemini 3.8 TTS launch is that cloning a voice from a sample lasting 30 seconds is now a standard developer feature. Google's safeguard is a matching spoken consent recording from the voice owner, plus SynthID watermarks and C2PA credential...

I was invited to test Gemini 3.8 Flash TTS. This is currently my favorite model. The voice outputs from this model are extraordinary. I never really rated AI voice generation because of the uncanniness associated with low quality. This Gemini IMO crosses that chasm, like Opus 4.5 did with coding,...
