Learning how to enable Voice Isolation on iPhone is super useful for phone calls and FaceTime audio and video calls. Despite being some of the best phones out there, iPhones haven’t traditionally been impervious to background noises affecting phone calls — after all, they use a microphone like every other phone, which just picks up everything it hears. Until now, that is, thanks to Voice Isolation.

By removing unwanted frequencies from your audio signal, Voice Isolation isolates your voice and cleans up what the person on the other end will hear. If you and your phone call partner are both using it, then well, you’re gonna be having some squeaky clean conversations. 

Voice Isolation has been around since iOS 15. However, originally it only worked on FaceTime audio and video calls. Now, with the release of iOS 16.4, you can use Voice Isolation on standard phone calls too, and we’re here to show you how.

We’ve done the steps below on FaceTime, but the steps are the same whether you’re using Voice Isolation on FaceTime or a phone call. 

How to enable Voice Isolation on iPhone

  •  Start a call using the Phone or FaceTime apps 
  •  Open Control Center 
  •  Tap the Microphone icon, then Voice Isolation 

Read on to see detailed instructions for each step.

    This seems like a good default candidate. I take it there’s no way to make this setting non-volatile?

    Perhaps it will be enabled first in Accessibility, since prioritizing voice frequencies and other such amenities (like custom equalization, mouse usage, triple-tap, LED alerts, back-tap) are the domain of the differently abled?
