Apple is rolling out significant enhancements to its AI-powered Siri in the latest iOS 27 developer beta, offering testers an early glimpse into a more personalized digital assistant. The third beta release of iOS 27, now available, activates previously announced voice controls for “Pace” and “Expressivity,” allowing users to fine-tune how quickly and emotionally Siri communicates.

This update is a key component of Apple’s broader initiative to re-engineer Siri using generative AI, aiming to deliver a more natural and personal user experience. Users can now select from various voices and accents, then utilize sliders to adjust Siri’s speaking speed and the degree of human-like emotion it conveys. To aid in customization, Siri will provide examples of common phrases, such as “You have one new message,” demonstrating the impact of different settings. While Apple’s new features mark a step forward, competitors like ChatGPT have offered more extensive voice customization options since December 2025, including adjustments for warmth, enthusiasm, and distinct conversational styles like friendly, professional, or quirky.

First unveiled at Apple’s Worldwide Developers Conference (WWDC 26), these voice controls expand beyond simple gender-based voice selection. The generative AI version of Siri is designed for deep integration across the updated iOS ecosystem. iPhone owners will have multiple ways to interact with the assistant, including speaking commands, swiping down from the Dynamic Island, tapping the device’s side button, or utilizing a new dedicated Siri application.

Alongside these major Siri improvements, iOS 27 beta 3 also includes minor updates, such as a refreshed Reminders app icon. However, some users have reported experiencing temporary issues after updating, including losing access to the new Siri features or their devices re-indexing data, a process typically associated with optimizing Siri AI for search functions.

Key Takeaways

• iOS 27 beta 3 introduces new "Pace" and "Expressivity" controls for Siri, allowing users to customize its speaking speed and emotional tone.
• This update is part of Apple's broader strategy to integrate generative AI into Siri, aiming for a more natural and personalized user experience.
• The enhanced Siri will be deeply integrated across iOS, accessible through various methods including a new standalone app, though some users have reported initial issues.
