iOS 27 Beta 5 Expands Siri Voice Customization to More Voices


Apple is giving Siri a little more personality with the latest iOS 27 beta.

With iOS 27 beta 5, Apple's new Siri voice customization tools are no longer limited to a small selection of voices. The company has expanded support for its Pace and Expressivity controls, allowing users to fine-tune how Siri speaks across a much wider selection of voices.

The update gives users more freedom to make Siri sound faster, slower, calmer, or more expressive depending on their preference.

Siri's New Voice Controls Are Becoming More Flexible

Apple first introduced the new Pace and Expressivity controls in earlier iOS 27 beta releases. Initially, however, the feature was restricted to two newly added Siri voices with American accents.

That limitation has now changed.

With beta 5, the customization tools work with additional American voices as well as Siri's existing British voices. In total, 11 Siri voices now support adjustments to speaking speed and expressiveness.

This makes the feature considerably more useful because users aren't forced to choose between a preferred voice and the ability to customize how it sounds.

What Are Pace and Expressivity Controls?

The two controls are designed to change different aspects of Siri's speech.

Pace determines how quickly Siri talks. If Siri feels too slow or difficult to follow, you can increase the setting. Conversely, lowering it can make responses easier to understand.

Expressivity changes the amount of emotion and emphasis in Siri's delivery. Increasing it can make responses sound more animated, while a lower setting creates a more restrained voice.

Both controls offer five adjustment levels, giving users plenty of room to find a combination that feels natural.

How to Change Siri's Voice Settings

Changing Siri's speaking style only takes a few taps.

Go to:

Settings → Siri → Voice

From there, select a supported Siri voice and adjust the Pace and Expressivity sliders until you find the sound you prefer.

The expanded selection means users now have significantly more control over one of the most noticeable parts of Apple's new Siri experience.

Which Devices Support the New Siri Voices?

The new voice technology isn't available on every Apple device.

Apple has indicated that its latest Siri voices rely on a more powerful on-device model, which means the hardware requirements are relatively demanding.

The supported devices include:

  • iPhone 17 Pro

  • iPhone 17 Air

  • iPad Pro with M4 or newer

  • Mac models with an M3 chip or newer and at least 12GB of RAM

Meanwhile, the broader Siri AI experience requires an iPhone 15 Pro or newer. Older compatible devices can still use Siri, but they rely on the previous voice synthesis technology rather than the newer system.

Setting Up a New Apple Device? Don't Forget Your Personal Data

As Apple continues adding personalized features to Siri, the overall setup experience becomes increasingly important when moving to a new device.

If you're upgrading to a newer iPhone or iPad, Smart Transfer can help simplify the process by moving important content from your previous device. Its photo gallery manager can help users organize and manage their images, while the app also provides tools for handling other personal files during a device transition.

Smart Transfer also includes utilities such as a Speed test app, along with Share Me file sharing capabilities for moving content between compatible devices. This can be useful when setting up a new Apple device and making sure your important photos, documents, and other files are ready to go.

Siri AI Is Still Coming Later This Year

The voice improvements are only one part of Apple's broader Siri overhaul.

The company is expected to introduce its more advanced Siri AI experience later this year. The upgraded assistant is designed to provide more capable responses and take advantage of Apple's newer on-device intelligence models.

For now, iOS 27 beta testers can experiment with the improved voice experience while Apple continues refining the software.

More Siri Customization Could Be Coming

The expansion in beta 5 suggests Apple is taking personalization seriously with the next generation of Siri.

Instead of giving every user the same voice experience, Apple is gradually allowing people to control how Siri sounds and behaves. The addition of more supported voices is a meaningful step because users can now customize the assistant without having to sacrifice their preferred accent or voice.

Of course, iOS 27 remains in beta, so Apple could make additional changes before the final release.

Final Thoughts

iOS 27 beta 5 makes Siri feel a little more personal by expanding Pace and Expressivity controls to a much larger selection of voices.

With 11 voices now supporting customization, users can adjust Siri's speaking speed and emotional delivery to better suit their preferences. The feature also gives us another glimpse at Apple's broader effort to make Siri feel more natural as its AI-powered overhaul approaches.

The stable iOS 27 release is expected later this year, and Apple still has time to refine the experience before the new Siri reaches everyone.
