If you want clearer calls in a noisy office, on a walk, or while working from home, Voice Isolation on iPhone can help reduce background noise and keep the focus on your voice.

This guide shows you how to turn on Voice Isolation on iPhone in iOS 18 and later, where to find it during a call, when it works, and what to do if the option does not appear.

Quick Answer

To enable Voice Isolation on iPhone:

  1. Start a supported call.
  2. Open Control Center during the call.
  3. Tap Phone Controls or the available audio controls.
  4. Select Voice Isolation.

If you do not see the option, check your iOS version, confirm the call type supports it, and try again while a call is active.

What You Need to Know First

  • Voice Isolation works on supported iPhone models and software versions.
  • For regular phone calls, you need iOS 16.4 or later.
  • For FaceTime and supported apps, availability can vary by device and app.
  • If you use speakerphone, Voice Isolation can sometimes make your voice sound choppy. In that case, switch to Standard or use your iPhone normally without speakerphone.
  • If you take work calls often, using a good headset with Voice Isolation usually gives the best results in noisy places.

Compatible Apple Devices

  • iPhone XR, iPhone XS, and later
  • iPad 8th generation or later
  • iPad Pro 11-inch models
  • iPad Pro 12.9-inch 3rd generation or later
  • iPad Air 3rd generation or later
  • iPad mini 5th generation or later
  • Mac models from 2018 or later
