Apple has added a new Voice Isolation feature to iPhone with the release of iOS 16.4, allowing users to block out ambient noise during a cellular call to make their voice be heard more clearly without distraction background noise.
With Voice Isolation enabled, the feature will filter out sounds around the user to allow their voice to be heard more clearly during a call, improving the microphone quality when the background environment is loud.
Voice Isolation has been available during FaceTime Audio Calls for some time, but never has the feature been available for regular cellular phone calls until now.
iOS 16.4 is the latest major update to Apple’s iOS 16 operating system, bringing enhancements, bug fixes, and security updates to iPhone.
In addition to Voice Isolation, iOS 16.4 introduces support for notifications on web apps added to the Home Screen, Crash Detection optimizations for iPhone 14 and iPhone 14 Pro models, over 20 new emojis, and more.
