Gemini 2.5 TTS Models: Enhanced Tone, Pacing & Multi-Speaker Control
The most significant announcement in the latest Google Gemini AI updates is the launch of two new text-to-speech models: Gemini 2.5 Flash TTS and Gemini 2.5 Pro TTS. These models introduce advanced voice modulation designed for more realistic AI-generated speech. Developers now have control over:
- Voice tone (calm, energetic, formal, conversational)
- Expressiveness (emotion-rich delivery)
- Pacing adjustments for dynamic narration
- Multi-speaker transitions for podcasts or dialogues
- Consistent voice identity across long-form audio
Google says these upgrades make the TTS systems ideal for:
- Virtual assistants with personality-driven voices
- Podcasts and audio storytelling
- Audiobooks with multi-character narration
- Interactive educational tools
- Localised audio content in diverse accents
Developers can now access the models through the Gemini API in Google AI Studio, expanding possibilities for building next-gen AI-powered voice applications.
Preferred Sources in Search Rolled Out Globally
One of the most user-impactful Google Gemini AI updates is the global rollout of Preferred Sources in Google Search. Earlier introduced in limited regions, this feature now enables users worldwide to choose their favourite news publishers so search results prioritise articles from those trusted outlets.
This is especially useful for readers who:
- Prefer verified journalism over random web sources
- Follow specific regional or language-based outlets
- Want consistent reporting from known publications
- Consume industry-focused news (finance, tech, healthcare)
Google also states that the “Preferred Sources” feature will appear in both:
- Search results pages
- AI Mode responses
When users view AI-generated summaries, the interface will now highlight content from selected publications more frequently, promoting better transparency and a more personalised news consumption experience.
More Inline Links in AI Mode & Gemini App
In response to criticism over insufficient source visibility, the latest Google Gemini AI updates significantly increase the number of inline citations shown inside AI-powered responses. This includes:

- Better visibility of subscription-based news sources
- Dedicated highlights for publisher content
This ensures users can verify information easily and access original reporting with fewer clicks. It also strengthens the overall web ecosystem by driving traffic back to publishers—an ongoing concern amid broader AI-driven summarisation trends.
Google Web Guide Expansion for Better Topic Discovery
Another improvement announced in the latest Google Gemini AI updates is the expansion of Google’s Web Guide experiment. This feature categorises search results into themed clusters to help users discover related topics faster, improving depth of research.
The Web Guide now offers:
- Faster load times
- More frequent appearance in Search
- Better grouping of contextual topics
- A cleaner user interface for navigation
For example, a search query about “AI speech models” might show grouped sections like:
- Latest TTS research
- Developer documentation
- Tech news updates
- Related AI tools
This makes Search more structured and user-friendly, aligning with Google’s long-term goal of transforming AI Mode into a fully research-ready experience.
Google’s New Partnership Program With Global News Publishers
Google has also announced a new commercial partnership program with news publishers worldwide. This is an important part of the Google Gemini AI updates, ensuring that journalism continues to be supported financially and technologically in an AI-led era.
