About Gemini 3.8 Flash TTS
Gemini 3.8 Flash TTS is Google's expressive speech model, released in September 2026. It reads a script word for word in one of 30 built-in voices and returns a WAV file. Google lists more than 100 supported languages and dialects.
The delivery is directed separately from the script. Write a style such as 'warm and slow, like a late-night radio host' and the model follows it for tone, pace, accent and emotion. Inline cues like <laugh> or <sigh> add those sounds at that point in the script.
Google marks every clip with SynthID, an inaudible watermark that identifies it as AI-generated. It is priced by the length of the text, so short lines cost very little.
Best for
- Voiceovers for social clips and product videos
- Narration with a specific mood, pace or accent
- Trying the same script in several voices to compare them
- Draft dialogue lines before a final recording
- Voiceovers in many languages
