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.
