Apple has introduced Siri Voice Controls in the latest iOS 27 developer beta, giving testers more ways to personalize the AI assistant. The update marks another step in Apple’s broader effort to make Siri feel more natural through generative artificial intelligence. Developers can now adjust how quickly Siri speaks and how much expression the assistant uses during conversations.
The latest iOS 27 beta activates the Pace and Expressivity settings that Apple previously listed as upcoming features. Users can now access these controls directly within Siri’s voice settings instead of waiting for a future software update. Consequently, developers can immediately explore the expanded customization options before the operating system reaches the public.
Apple first introduced these voice personalization features during its Worldwide Developers Conference in June. Since then, the company has continued refining Siri as it prepares a major AI-focused upgrade for iPhone users. The latest beta demonstrates Apple’s commitment to improving everyday interactions with its digital assistant.
Users can select from multiple Siri voices featuring different accents and speaking styles. After choosing a preferred voice, they can move sliders that control speaking speed and emotional expression. As a result, each user can create a Siri experience that better matches personal preferences and communication styles.
While adjusting these settings, Siri provides spoken sample phrases that demonstrate every change in real time. For example, the assistant may say, “You have one new message,” allowing users to hear the selected voice before saving their preferences. This immediate feedback helps developers fine-tune the experience without guessing how each adjustment sounds.
The upgraded Siri also supports several methods for starting conversations. Users can speak directly to the assistant, swipe down from the Dynamic Island to type requests, press the side button, or launch the dedicated Siri application. Therefore, Apple offers greater flexibility for different situations and user preferences across the operating system.
Siri Voice Controls represent one part of Apple’s wider strategy to modernize its digital assistant with advanced AI technology. The company aims to deliver more natural conversations while giving users greater influence over how Siri communicates. These improvements could make everyday interactions feel more personal and engaging.
In addition to Siri enhancements, iOS 27 beta 3 introduces several smaller interface updates. Apple refreshed the Reminders application icon as part of the latest developer release. Meanwhile, some beta testers reported temporary issues after installing the software, including losing access to the upgraded Siri experience. Others noticed their devices began indexing stored information again, a process commonly associated with preparing AI-powered search features and optimizing system performance.
As testing continues, Apple will likely refine these features based on developer feedback before the official public release. The company frequently updates beta software to improve stability, resolve reported issues, and enhance new capabilities. Siri Voice Controls will remain one of the most anticipated additions as Apple advances its AI-powered ecosystem across future iPhone devices.
