Get ready to experience Siri like never before! Apple is giving developers an exciting sneak peek into the future of its AI-powered assistant with the latest iOS 27 developer beta. This update introduces groundbreaking controls that allow you to fine-tune how Siri sounds, making your digital companion feel even more personal and natural.
Specifically, in iOS 27 beta 3, Apple has officially enabled the highly anticipated “Pace” and “Expressivity” voice controls. These options, which were previously labeled as “Coming soon” in earlier beta releases, are now live for testers, inviting them to customize Siri’s vocal delivery.
Siri Gets a Personality Boost
This significant update is part of Apple’s broader mission to completely rebuild Siri around advanced generative AI. The goal is to evolve Siri from a functional tool into a truly intuitive and personal assistant that understands and responds with more human-like nuance. Allowing users to customize Siri’s voice is a crucial step in fostering this deeper connection with the new technology.
Gone are the days of simply choosing a male or female voice for Siri. First unveiled at Apple’s Worldwide Developers Conference (WWDC 26), these new controls offer a far richer personalization experience. Beta testers can now experiment with a variety of voices, including those with different accents, and truly sculpt Siri’s sound.
Two new sliders are at your fingertips: one for “Pace” and another for “Expressivity.” The Pace slider lets you adjust how quickly or slowly Siri speaks, ensuring commands and information are delivered at your preferred speed. Meanwhile, the Expressivity slider allows you to control the level of human-like emotion and warmth conveyed in Siri’s voice, making interactions feel more engaging.
To help you find the perfect blend, Siri will provide immediate feedback as you make adjustments. It will practice common phrases, such as “You have one new message,” giving you an instant sense of how your chosen settings and voice sound in real-time. This iterative process makes customization both easy and enjoyable.
Comparing Siri to Other AI Voice Assistants
While Apple is making impressive strides, other AI voice assistants are also advancing rapidly in this space. For instance, ChatGPT offers even more extensive voice customization options, which rolled out in December 2025. Users can adjust parameters like “warmth” and “enthusiasm” to further personalize the AI’s delivery.
Beyond these, ChatGPT also provides options to configure the AI’s base style and tone, allowing it to sound more friendly, professional, candid, or even quirky. These stylistic choices influence not only how ChatGPT speaks but also the overall manner in which it presents information to the user, offering a truly tailored interaction.
Deeper Integration Across iOS
The new, AI-powered version of Siri is designed for seamless and deep integration across the entire updated iOS ecosystem. iPhone users will have multiple convenient ways to interact with their intelligent assistant, making it more accessible than ever before. You can simply speak to start a conversation, as usual.
Alternatively, you can swipe down from the Dynamic Island at the top of your screen and type your query, offering a discreet way to engage. Tapping the phone’s side button will also invoke Siri, or you can even utilize the brand-new standalone Siri app, providing a dedicated interface for your AI companion.
Other Beta 3 Updates and What to Watch For
Beyond the exciting Siri enhancements, iOS 27 beta 3 also introduces a few other minor updates. One noticeable change is an updated icon for the Reminders app, offering a fresh visual tweak to a familiar utility.
However, as with any beta software, there are always a few kinks to iron out. Some users on X (formerly Twitter) have reported experiencing issues after updating, including losing access to the new Siri features or their iPhone beginning to re-index data. This re-indexing is often a common first step in optimizing Siri AI for search, but it can temporarily affect performance. Beta testers should always proceed with caution and be aware of potential instabilities.
