Tips on how to improve iPhone call sound quality

Calling is an important basic function of a mobile phone, and Apple is obviously very concerned about this. When you're on a call on iPhone, a feature called Voice Highlight that allows your voice to come through more clearly to the person you're talking to, even in noisy environments.

In iOS 15 and later, Apple has added a number of features that make it possible to use the FaceTime function for video conferencing with other video calling apps. Better performance on iPhone.

One of these features is Voice Highlight, which makes it easier for people to hear your voice during video calls. The feature also works on regular phones on devices running iOS 16.4 and above.

#When you're on a call, your device's microphone typically picks up a variety of sounds in the environment. However, with Voice Highlight, machine learning can differentiate between these sounds, blocking out any ambient noise and prioritizing your voice so it comes through more clearly.

#This feature supports iPhone XR and iPhone XS series models to update devices. Here are the steps to enable:

#1. Open the Phone app and start a regular audio phone call with someone.

#2. After the call, pull down the Control Center by dragging down from the upper right corner of the screen.

#3. Click the microphone mode button at the top.

4. Select "Voice Highlight".

You can turn it off at any time by visiting Control Center again and selecting the "Standard" option.
