iOS 16.4 Adds Voice Isolation for Cellular Phone Calls

The iOS 16.4 update that is set to be released to the public in the near future includes voice isolation for cellular calls, according to notes that Apple shared today.

voice isolation
Apple says that Voice Isolation will prioritize your voice and block out the ambient noise around you, making for clearer phone calls where you can better hear the person you're chatting with and vice versa.

Voice Isolation has been available for VoIP calls that use FaceTime, WhatsApp, and other apps on devices running iOS 15 or macOS Monterey or later, and it is designed to significantly improve microphone quality when on calls by cutting down on background noise. Until now, it was not available for cellular conversations, with Apple offering no way to improve call quality.

On a ‌FaceTime‌ call, Voice Isolation can be enabled by activating control center, tapping on the Mic Mode option, and choosing the Voice Isolation option, so the feature may be able to be activated in a similar way for voice calls.

Other iOS 16.4 features include new emojis, Push Notifications for web apps, bug fixes for HomeKit, Crash Detection optimizations, and more.

Finally!!! It irked the hell out of me that voice isolation is supported for every other form of voice calls besides cellular. Which I use the most, and I am sure others do to. I don't get why they didn't release this support at launch of the voice isolation feature.

This will greatly increase the clarity of calls between iphone users overall. This update should also dramatically increase voice clarity while using airpods!
