Apple has released the third iOS 27 developer beta, introducing new voice controls that allow users to adjust the pace and expressivity of Siri AI. This update expands on the features unveiled at WWDC, including Liquid Glass customizations and deeper integration of Apple Intelligence across the device.
What new features are included in the iOS 27 beta 3?
The primary addition in this developer beta is the expansion of Siri AI’s customization. According to the update, users can now utilize voice controls for “Pace” and “Expressivity,” which dictates how quickly Siri speaks and the emotional tone of its responses. Siri AI is integrated throughout the operating system, accessible via the Dynamic Island and a dedicated Siri app.
The update also includes new Liquid Glass customization options. These visual enhancements are part of the broader iOS 27 redesign aimed at providing more personalized interface elements.
Comparing iOS 27 Beta 2 and Beta 3
While beta 3 focuses on the vocal nuances of the virtual assistant, previous iterations established the foundation for the new OS. For comparison, iOS 27 beta 2 introduced several distinct features that differ from the current release:

- Beta 2: Added a dedicated “Write with Siri” button on the keyboard, Apple Wallet Insights, and updates for iPhone-to-Android RCS chats.
- Beta 3: Focuses on Siri’s vocal delivery (Pace and Expressivity) and Liquid Glass customization.

Apple’s compatibility list for iOS 27 is extensive, supporting hardware dating back to 2019. The following models can install the developer beta:
