Make yourself easier to hear on cellular iPhone calls

On iPhone, Apple offers Voice Isolation for use during calls over cellular networks. Read on to learn how to use and enable this feature.

In iOS 15 and later, Apple has included several new features to make video conferencing using FaceTime and other video calling apps more attractive. One of the features, called Voice Isolation, makes it easier for people to hear you on video calls, and in iOS 16.4 and later, it also works on regular phone calls.

When you're on a call, your device's microphone typically picks up various sounds in the environment, but with Voice Isolation, machine learning can differentiate between these sounds, blocking out any ambient noise and prioritizing your voice for clarity pass.

The following steps show you how to enable Voice Isolation during regular calls on an iPhone running iOS 16.4 or later.

1. Open the Phone app and start a recurring audio call with someone.
2. After the call, drag Control Center diagonally downward from the top right corner of the screen (if your iPhone has a Home button, swipe up from the bottom).
3. Click the microphone mode button at the top.
4. Select the "Voice Isolation" option.

Voice Isolation will now be activated and you can turn it off at any time by visiting Control Center again and selecting Standard.

When Apple originally launched Voice Isolation for FaceTime, it also launched another audio option called Wide Spectrum, which the company says can pick up “the entire symphony of sound – your voice and your Everything around”. Essentially, this mode brings every sound into your call, perfect for when you want the other person to hear everything that's going on in your space. Note that "Broad Spectrum" does not apply to regular phone calls, it only applies to FaceTime calls.
