Apple's iPhones include a calling feature that can make your voice clearer to the person you're speaking to when on a call, even when you're in a busy environment. It's called Voice Isolation, and here's how it works.
One of these features, called Voice Isolation, makes it easier for people to hear your voice on a video call, and on devices running iOS 16.4 later, it works for regular phone calls, too.
When you're on a call, your device's mic usually picks up a wide range of sounds in the environment, but with Voice Isolation, machine learning distinguishes these sounds, blocks out any ambient noise and prioritizes your voice so that it comes through clearly.
The following steps show you how to enable voice isolation during a regular phone call on iPhone XR, iPhone XS, and newer models of iPhone.
- Open the Phone app and start a regular audio phone call with someone.
- Once you're in the call, pull down the Control Center by dragging down diagonally from the top-right corner of the screen.
- Tap the Mic Mode button at the top.
- Select the Voice Isolation option.
Voice Isolation will now be activated, and you can turn it off at any time simply by accessing the Control Center again and selecting Standard.
When Apple introduced Voice Isolation for FaceTime, it also debuted another audio option called Wide Spectrum, a feature that the company says can pick up "an entire symphony of sound – your voice and everything around you."
Essentially, this mode brings every single sound into your call, making it ideal for when you want the other person to hear everything that's happening in the space you're in. As of writing, Wide Spectrum isn't available on regular phone calls, but Apple may expand it to the Phone app in the future.
