Voice isolation is a valuable feature that Apple introduced in iOS 15. It allows you to block out background noise during video calls. However, it was limited to FaceTime and other supported video calling apps. In iOS 16.4, Apple made voice isolation available for cellular phone calls as well.
In this guide, I am going to walk you through a step-by-step guide on how to enable and use Voice Isolation on your iPhone for cellular calls.
What is Voice Isolation and how does it work?
Voice isolation is a feature that allows you to block out background noise when you’re on a phone call. This can be helpful if you’re in a noisy environment or if you want the other person to hear you more clearly.
Voice isolation uses the microphone on your iPhone to pick up your voice and then filters out background noise. This is done by using a technique called “beamforming,” which focuses the microphone’s pickup pattern on your voice.
How to Enable Voice Isolation for cellular calls on iPhone
To enable voice isolation on your iPhone, follow these steps:
1. To begin with, make sure that your iPhone is updated to iOS 16.4. This is a must-have requirement as the iOS versions prior to this one are not supported for Voice Isolation for Cellular calls.
You can check for Software updates on your iPhone by going to the Settings app and then navigating to General > Software Update. If the iPhone is on iOS 16.4 then you are good to go.
2. Once your iPhone is on iOS 16.4 or later, head over to the Phone app and connect to a cellular audio call to anyone as you usually do.
3. Once the call is connected, swipe down from the top-right edge of your iPhone to open up the Control Center.
4. In the control center, tap on the Mic Mode tile located in the top-right corner of the screen.
5. Next, tap on the Voice Isolation option to enable it. Once it’s enabled, it will get a checkmark next to it.
Once done, you’ll see the Voixe Isolation in action immediately. As described above, you’ll observe that the unwanted noise is now either eliminated or suppressed to a very high extent.
If you want to disable the Voice Isolation, follow the same steps as mentioned above i.e. go to the Control Center > Mic Mode > select the Standard Option.
For those who are unfamiliar, Wide Spectrum (one of the Mic Modes) is designed to let you hear the entire range of sound. Unfortunately, it doesn’t support cellular phone calls even in iOS 16.4. I hope Apple makes it possible sooner than later.

When you enable voice isolation, the sound quality of your phone calls may improve. This is because the microphone is able to pick up your voice more clearly and filter out background noise. However, some people find that voice isolation can make their voice sound a bit muffled.
When should I use voice isolation?
You should use voice isolation when you’re in a noisy environment and you want the other person to hear you more clearly. You can also use it if you’re in a quiet environment and you want to make sure that the other person doesn’t hear any background noise.
