Way back in iOS 15, Apple added a Voice Isolation option to FaceTime calls to filter out noise around you while you’re talking, which is a boon if you’re making a call in a loud space or outside environment. With the recently released iOS 16.4, Apple has now brought that feature to cellular calls as well, but it’s not an option in the Settings app as you might expect. Instead, during a call, open Control Center by swiping down from the top right of the screen (Face ID iPhones) or up from the bottom (Touch ID iPhones). Then tap the Mic Mode button and Voice Isolation. You won’t hear any difference, but the person on the other end should be able to hear you better. iOS remembers your setting, so switch back to Standard when you’re done—When you're in a quiet place Voice Isolation may make your voice sound more processed.
If you want to capture surrounding sounds, Wide Spectrum is available for supported FaceTime calls and certain third-party calling apps. It is not available for cellular Phone calls; use Standard if you do not want Voice Isolation during a phone call.
