When you make a phone call with someone, you may hear noises from the background. If you are irritated about this, you come to the right place. This is what Voice Isolation can do for you. This post is a complete guide on Voice Isolation on iPhone.

What is Voice Isolation on iPhone?

The "Voice Isolation" feature on the iPhone refers to a technology that optimizes the audio input experience in specific scenarios, especially during FaceTime or phone calls. Specifically, When the iPhone's Voice Isolation feature is enabled, it prioritizes capturing and amplifying the user's voice while minimizing or eliminating background noise. Voice Isolation uses the iPhone's built-in microphone noise suppression algorithm and audio processing capabilities to highlight foreground speech, making the call heard more clearly by the other party.

Where can Voice Isolation be used:

  • Voice Isolation is especially useful for clear calls in noisy environments, such as in streets or environments with background conversation.
  • In public places, this feature helps block the voices of people around you from hearing your conversation. It can increase the privacy of the call and protect personal privacy.
  • In business meetings or remote working scenarios, clear voice calls reduce information transmission errors. It improves meeting efficiency, and makes remote collaboration more efficient.
  • For users with sensitive hearing or who have difficulty distinguishing speech from noise, the Voice Isolation function reduces the difficulty of hearing identification and relieves the burden on the ears.

Things Related to Voice Isolation on iPhone

In addition to Voice Isolation, you can see "Wide Spectrum" on the Mic Mode selection screen. Let's know what Wide Spectrum is.

Wide Spectrum captures a wide spectrum of surrounding audio, including not only the sound of the user but also other sounds in the environment. These sounds are like background music, conversation, or ambient noise. Wide Spectrum contrasts with Voice Isolation, which focuses on clearly capturing the user's voice and reducing background noise.

The wide spectrum mode provides a more natural audio environment experience during FaceTime calls or recordings. It is suitable for those situations where you want to retain or need to include ambient sounds. For example, if you are recording a live speech at a concert or conducting an interview outdoors, you can turn on Wide Spectrum mode. It lets your audience feel the atmosphere of the scene.
