Latest iOS 27 Beta Expands Siri AI Voice Customization

MacRumors • Mon, 10 Aug 2026

With the fifth beta of iOS 27 , Apple has expanded the voice customization options for Siri AI. Pace and Expressivity can now be adjusted for more of the available voice options instead of just the two American voices. There are seven American voice options and four British voices to choose from, all of which can be customized with different Pace and Expressivity settings. Pace changes talking speed, while expressivity changes emphasis. &zwnj;Siri&zwnj; AI voice customization is done on-device, so the feature is limited to newer iPhones. You need an iPhone 17 Pro , &zwnj;iPhone 17 Pro&zwnj; Max, or iPhone Air to use voice customization on an iPhone. It's available on Macs with an M3 chip or newer and at least 12GB RAM, and the M4 iPad Pro and newer, also with at least 12GB RAM.

iOS 27 Beta 5 Brings New Icons for Siri, Safari, Settings and More

In the fifth beta of iOS 27 , Apple is continuing to make design tweaks. There are updated Liquid Glass icons for Safari, the Siri app, Settings, Remote, App Store , and Preview. The Safari icon is a brighter blue with more detailed compass lines and arrows, while the &zwnj;Siri&zwnj; icon looks more like the actual &zwnj;Siri&zwnj; bubble that's displayed when &zwnj;Siri&zwnj; is activated. The &zwnj;App Store&zwnj; app icon is more translucent so you can better see each line making up the A, Settings uses more translucency, and Preview has an entirely different look with a loupe over a colorful background. The Remote icon also has more detail and it's been updated with a gray background instead of black. Some app icons were updated with the initial &zwnj;iOS 27&zwnj; beta release, including Maps, Photos , and Weather, but others kept their iOS 26 look. It's possible Apple will overhaul even more icons in upcoming betas, because the company said it was planning to give icons an updated layered look to better fit the Liquid Glass aesthetic. &zwnj;iOS 27&zwnj; will be released in just about a month.

Apple Cutting Back 2026 Hardware Shipments Due to Memory Shortage

Apple is scaling back its hardware shipment plans in 2026 due to DRAM shortages, Apple analyst Ming-Chi Kuo said today . Kuo made the comment in a longer piece disputing a recent report suggesting TSMC has $1 billion of unpackaged processors waiting on memory chips that Apple has been unable to secure. Kuo said Apple plans processor production at least three months in advance based on the amount of memory expected to be available, and it does not have TSMC build large numbers of wafers ahead of time. He believes there are indeed memory shortages, but no situation where TSMC is sitting on unused inventory. In other words, tight memory supply is real. But my understanding is that there has been no dramatic scenario in which TSMC first built up US$1 billion of WIP and then had to wait for memory to arrive before packaging could proceed. TSMC and Apple are both known for world-class execution, and such a dramatic development would be unusual given how closely the two companies coordinate their supply chains. Memory shortages have already affected the Mac Studio , Mac mini , and MacBook Air , and it sounds like ongoing supply problems will also impact the upcoming iPhone models. Memory makers have been prioritizing supply for AI data centers because contracts for those chips are more profitable, leaving less capacity available for consumer device chips. A lack of supply has driven prices up and led to long wait times for some products. Apple raised prices on all of its Macs and iPads in June, and iPhone prices are expected to go up in September. The iPhone 18 Pro , &zwnj;iPhone 18 Pro&zwnj; Max, and foldable iPhone Ultra could be available in limited quantities because of the memory problems, and we expect the devices will sell out during the preorder period.
