Apple this week released the third developer beta of iOS 27, and it enables a new feature that is compatible with only three iPhone models.
Specifically, the third beta allows you to customize the pace and expressiveness of Siri’s voice, but only on the iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air, given that the feature currently requires an iPhone model with 12GB of RAM. The standard iPhone 17 and all other iPhone models are equipped with 8GB of RAM or less.
The higher amount of RAM is required because the feature is powered by Apple’s largest and most advanced on-device AI model ever, AFM 3 Core Advanced.
iOS 27 should be released in September. A public beta will be available later this month.
