How to Enable Voice Isolation on iPhone to Improve Call Quality

Do you often get complaints from people you call about background noise on a call? If yes, the new iOS 16.4 update has brought a cool feature called Voice Isolation, which can isolate your voice, eliminating any noise from your surroundings while you’re on the call. Simply put, it cuts down all the background noise coming from your surroundings and ensures your voice is heard clearly on the other side of the call. 

You might not be aware but your iPhone’s mic usually picks a wide range of sound from your surrounding while you’re on a call. But with the Voice Isolation mode available on iPhone, machine learning quickly differentiates between your voice and the ambient noise coming from the background. Enabling this feature results in eliminating the background noise while isolating your voice. As a result, the other person can clearly hear your voice, no matter how noisy the environment you’re in. 


It’s not the first time we have heard from Apple about Voice Isolation on iPhones. The feature was initially introduced in September 2021, but only for FaceTime or VoIP calls. But with iOS 16.4, Apple has made this feature available for normal phone calls too. The company says that it has been rolled out to improve the regular call quality. 

Since you’re here, we are assuming you want to learn more about the Voice Isolation feature.

How does Voice Isolation work on iPhone and what is it?

If you are thinking about what Voice Isolation on iPhone means, first of all, it’s not a new feature. This feature was part of iOS 15 but was there solely for removing background noise from FaceTime and VoIP calls. Some of you may think about what Voice Isolation does. To explain that, you need to understand the noise cancellation feature which is aimed at canceling noise, but they are not the most effective option when you’re in traffic or on a busy subway. But with the Voice Isolation feature, Apple aims to cut down background noise while prioritizing your voice so the other person can hear you loud and clear

So, the next obvious question is how Voice Insolation works on iPhone. Thanks to machine learning, it quickly distinguishes between your voice and background noise and blocks it effectively to isolate your voice. If you are new to this, noise cancellation has been part of Android phones for a long time. But, there was no explanation for why Apple didn’t feature noise cancellation for regular calls even on the flagship models like


iPhone 13 series and iPhone 14 series. As we write, the new feature has been received well by iOS 16 users and tech pundits across the web.

  • Voice Isolation: Voice Isolation mode cuts down the background noise and isolates your voice. As a result, the other person on the call will hear everything you say loud and clear. The conversion remains hassle-free on the Voice Isolation mode. 
  • Wide Spectrum: This mode allows hearing the other person every bit of sound captured by the mic from your surrounding. 

Step #4: On this screen, you should choose the ‘Voice Isolation” option and simply continue with the call.
