Today Google announces significant improvements to the Gemini 2.5 Flash and Gemini 2.5 Pro Text-to-Speech models, designed to give you more control over style, pacing, and voices in complex scenarios.
What changes in Gemini 2.5 TTS
Google releases two new models in preview: Gemini 2.5 Flash TTS (optimized for low latency) and Gemini 2.5 Pro TTS (optimized for quality). These replace the TTS models they published in May and are already available to try in Google AI Studio, the Playground, and via the Gemini API.
Key points:
- Richer expressiveness and better adherence to style instructions.
- Context-aware pacing control.
- More consistent multi-speaker dialogues and multilingual capabilities.
Technical improvements and why they matter
If you work on audiobooks, e-learning, product tutorials, or podcasts, you know a voice has to do more than read text: it has to interpret. These updates address three critical layers.
