    Steps on iOS 15 to enable Voice isolation on FaceTime

    The Mic Mode setting only appears when you're actually on a voice or video call. It won't appear in the Control Center in any other situation.

  6. Swipe away to dismiss Control Center and return to the call.

  7. Voice Isolation is now active on the call.

What Does Voice Isolation Do?

Voice Isolation is a new mode on iOS 15 which aims to separate your voice from any background noises occurring during FaceTime calls. It helps your voice remain in focus throughout the call, silencing any ambient noises around you.

It achieves this through advanced machine learning so your iPhone is able to detect what's your voice and what is background noise.

By doing so, the focus is placed on your voice rather than what's going on around you which can be particularly useful when taking a call somewhere busy or noisy. Effectively, it's a form of personalized noise cancellation for the recipient of your call. 

Why Would You Use Voice Isolation Mode?

Voice Isolation mode is useful in various situations throughout your daily life. Here's a look at some of the best examples.

  • When taking a call somewhere noisy. If you're taking a FaceTime call while walking down a busy street, it can be hard to be heard. By using Voice Isolation, you can cancel out background noise more effectively than before.
  • When calling someone with hearing issues. If you're calling someone with hearing issues, Voice Isolation will help elevate your voice so they can hear you more clearly. 
  • When wanting a crisper call. FaceTime typically delivers fairly crisp sounding calls but Voice Isolation makes the calls sound even clearer. Turning it on is a win-win situation. 

Does Voice Isolation Work With Other Apps?

The technology is there for Voice Isolation to work with other third-party apps so it's not exclusive to FaceTime. However, it requires the feature to be enabled by the app developer and at this time, there aren't any alternatives out there. Expect to see it introduced elsewhere soon.

Does Voice Isolation Work With Older iPhones? 

Voice Isolation requires an A12 Bionic chip or newer so it isn't available on iPhone X or older devices.
