Apple has given Siri one of its biggest upgrades yet in iOS 27. Alongside a more conversational Siri AI experience, users can now customize how Siri sounds by adjusting its voice expressivity and speaking pace. This means Siri can sound more energetic, more relaxed, faster, or slower depending on your preference. Apple says the feature is part of Siri’s new voice experience and allows users to make Siri feel more natural and personal.
If you have updated to iOS 27 and want to personalize Siri’s voice, this guide walks you through every available option.

How to Change Siri’s Voice in iOS 27
Before adjusting pace and expressivity, you can choose a different Siri voice.
The Siri Voice settings page has been redesigned in iOS 27 and now places all voice controls in one location. Apple has also introduced a more streamlined interface for selecting voices and customization options.
- Open Settings on your iPhone.
- Scroll down and tap Apple Intelligence & Siri (or Siri settings, depending on your device).
- Tap Siri Voice.
- Select your preferred voice from the available options.
- Choose a voice variation if available.
- Wait for the voice preview to play before making your final selection.
How to Customize Siri’s Expressivity in iOS 27
Expressivity controls how much emotion and emphasis Siri uses while speaking. A higher setting makes Siri sound more expressive and conversational, while a lower setting creates a more neutral voice.
Apple introduced this feature as part of the new Siri AI experience and provides a dedicated slider for fine-tuning the assistant’s personality.
- Open Settings.
- Go to Apple Intelligence & Siri.
- Tap Siri Voice.
- Find the Expressivity slider.
- Drag the slider left for a calmer tone.
- Drag the slider right for a more expressive voice.
- Listen to the voice preview.
- Continue adjusting until you find the sound you prefer.
How to Adjust Siri’s Speaking Pace
Some users prefer Siri to speak quickly, while others find a slower pace easier to understand. iOS 27 now allows direct control over Siri’s speaking speed.
The new Pace slider gives users more flexibility than previous versions of Siri.
- Open Settings.
- Tap Apple Intelligence & Siri.
- Select Siri Voice.
- Locate the Pace slider.
- Move the slider left to slow Siri down.
- Move the slider right to make Siri speak faster.
- Listen to the sample playback.
- Fine-tune the setting until it feels comfortable.
How to Combine Voice, Expressivity, and Pace Settings
For the best experience, experiment with all three controls together.
Many users will find that changing only one setting is not enough. A slower pace with higher expressivity can sound more conversational, while a faster pace with lower expressivity creates a more professional tone.
Suggested Combinations
- Natural Conversation
- Medium pace
- High expressivity
- Professional Assistant
- Medium pace
- Low expressivity
- Fast Responses
- High pace
- Medium expressivity
- Easy Listening
- Slow pace
- Medium expressivity
Device Requirements
Not every iPhone running iOS 27 can use the new voice customization controls.
Apple currently limits the advanced Siri voice customization experience to devices that support its latest on-device AI models. Reports indicate support is available on newer hardware, including the latest Pro iPhones and select iPads, Macs, and Vision Pro models.
If you do not see the Pace or Expressivity sliders, your device may not support the feature yet.
