Apple adds Siri voice customization to iOS 27 beta 3

Apple has activated new voice customization controls for its redesigned Siri AI in the latest developer test version of its upcoming mobile operating system. The feature, which allows users to adjust the speaking pace and expressiveness of the digital assistant, is now live in iOS 27 beta 3, released on July 6, 2026.

The update enables two previously dormant sliders in the device settings, offering five adjustment levels for each of the two currently available Siri voices.

Once a preferred setting is selected, it is saved and will also apply to spoken directions in Apple Maps and Safari. The company first previewed this level of voice personalization during its Worldwide Developers Conference keynote in early June.
