What Is Voice Isolation and How Does It Works

As the name tells, the voice isolation feature filters out all the ambient/ background noise in your surrounding and prioritizes your voice to deliver a clear calling experience during a conversation. Voice isolation technology uses artificial intelligence to recognize background noise and prioritize your voice during a phone call.

By default, cellular calls on an iPhone use the standard mic mode, which also delivers every background noise along with your voice to the recipient. However, once you enable the voice isolation mode, the iPhone’s mic removes any noise and delivers only your crystal clear voice during the call.

Basic Requirements to Use iPhone’s Voice Isolation Mode

You need to fulfill the following prerequisites to use the voice isolation feature on your iPhone:

  • An iPhone with the A12 Bionic chipset or above, i.e. an iPhone XS or higher model.
  • Make sure iOS 16.4 is installed on your iPhone. So, please update your iPhone to the latest build before you proceed further.

How to Enable Voice Isolation on iPhone with iOS 16.4

With all the basics out of the way, here’s how you can enable voice isolation for phone calls on your iPhone:

1. During an ongoing call, swipe down from the top right corner of the screen to bring up the “Control Center.”

2. In the Control Center, tap the “Mic Mode tile present at the top right corner.

3. Once you select the Mic Mode option, you will get three options to choose from:

  • Standard Mic: This is the default option and doesn’t filter out noise
  • Voice Isolation: This mode isolates the background sounds on iPhone and allows others on the call to hear your voice clearly.
  • Wide Spectrum: This mode is designed to capture every sound by the mic into your call. However, as you can see below, the wide spectrum mode is currently unavailable.

4. Here, choose the “Voice Isolation” option and return to your phone call. You can now ask the recipient if they notice a change in your voice and if the background noise is gone.

Note: The voice isolation mode is only enabled for a particular phone call. The “Mic mode” will automatically switch to standard mode once the call ends. You will need to enable voice isolation for each phone call individually.

We thoroughly tested this feature, and the results were pretty impressive. Turning on the voice isolation mode significantly improved the voice call experience, even when we were in our office’s bustling surroundings.
