When enabled, Voice Isolation eliminates background noise that interferes with your phone calls. That way, if you’re running errands or hanging out with friends, you won’t be disturbed by a barking dog or construction outside your home.
To enable Voice Isolation, you must be on a call because the feature isn’t in Settings. Once activated, Voice Isolation will remain on for all future calls unless you manually turn it off.
Here’s how to activate and deactivate phone voice isolation.
How to enable voice isolation
1. Click your Telephone app.
2. While on a call, swipe down from the top right corner of the screen to access your control center.
3. tap Telephone control Near the top of the screen.
4. tap sound isolation.
To disable Voice Isolation, follow the same steps above and click standard In phone control. This will return your microphone to its default settings.
What is broad spectrum?
In addition to voice isolation in phone control, you’ll also find wide spectrum. Unlike speech isolation, which suppresses background sounds, wide spectrum amplifies background sounds without affecting your voice.
A wide spectrum is useful for talking to multiple people over a single phone line. This way, everyone’s voice can be heard, not just the person holding the phone.
Currently, broad spectrum is only available for FaceTime call. Since the feature is still present in Phone Control, it may be available for phone calls in the future.
