iOS 27 Beta 3: Siri Now Supports Pace and Expressivity Customization
Original: You can now customize Siri’s pace and expressivity in the latest iOS 27 beta
Why This Matters
Apple's generative AI Siri rebuild intensifies competition with ChatGPT and other voice AI assistants.
Apple released iOS 27 developer beta 3 on July 6, 2026, enabling Siri voice controls for 'Pace' and 'Expressivity.' Previously marked 'Coming soon,' these sliders let users adjust how quickly and emotionally Siri speaks, as Apple rebuilds the assistant around generative AI.
Apple's iOS 27 developer beta 3, released July 6, 2026, activates two Siri voice customization controls — 'Pace' and 'Expressivity' — that had been listed as 'Coming soon' in earlier beta builds. Users can now adjust how quickly Siri speaks and how much human-like emotion its voice conveys, using sliders within the settings. As adjustments are made, Siri previews the selected settings by speaking sample phrases such as 'You have one new message.' The feature was first announced at Apple's WWDC 26 in June 2026 and expands Siri personalization beyond simply choosing a male- or female-sounding voice, now also supporting multiple accents. By comparison, ChatGPT rolled out similar voice customization in December 2025, including warmth, enthusiasm, and tone adjustments (friendly, professional, candid, or quirky), which also affect how information is presented. The new AI Siri is accessible via voice, Dynamic Island swipe, side button, or a new standalone Siri app. Some users on X reported losing access to the new Siri or seeing data re-indexing after updating to beta 3.
