Apple has introduced new features in iOS 27 beta 3 that allow beta testers to customise the ‘Pace’ and ‘Expressivity’ of Siri’s voice. This follows the company’s announcement at WWDC 2026, where it outlined plans for enhanced AI capabilities in its virtual assistant. The latest beta version provides a hands-on preview of these changes, which were previously listed as upcoming but not yet available for testing.

The update comes as part of Apple’s ongoing efforts to refine Siri’s AI-driven interactions. The ‘Pace’ and ‘Expressivity’ sliders give users greater control over how Siri speaks, allowing for a more natural and personal experience. These features were first hinted at during the WWDC 2026 keynote, where Apple emphasized its commitment to improving the user experience of its AI-powered tools.

The introduction of these controls marks a significant step in Apple’s development of Siri. The feature was previously listed as ‘Coming soon’ in the first beta release of iOS 27, but it is now fully enabled in beta 3. This update is part of a broader trend in AI assistant development, where personalisation and user control are becoming central to the user experience.

The ability to customise Siri’s voice may influence user adoption and satisfaction with the assistant. As AI assistants become more integrated into daily life, features like these can impact how users interact with and rely on such tools. However, the success of these changes will depend on how well they are implemented and whether they address user needs effectively.

While the feature is still in development, its inclusion in beta 3 suggests that Apple is moving quickly to refine Siri’s capabilities. The company has a history of iterating on features based on user feedback, and this update may be just the beginning of further enhancements. As the beta progresses, more details about the final implementation are likely to emerge.
