Clear audio communication is paramount in today’s digital landscape, especially in virtual meetings and online collaborations. Background noise can disrupt conversations, leading to misunderstandings and reduced productivity. Platforms like Zoom and applications like Krisp have developed advanced noise isolation features to address this.

This article delves into Zoom’s Personalized Audio Isolation and Krisp’s Background Voice Cancellation features, exploring their functionalities, benefits, and how they enhance virtual communication.

What is Personalized Audio Isolation?

Zoom’s Personalized Audio Isolation feature is designed to better differentiate the speaker’s voice from background noise, even in noisy environments like open offices or homes with ambient distractions. The feature employs voiceprint technology to enhance the clarity of your speech during virtual meetings.

How Does It Work?

Automatic Voiceprint Creation

• • Once you enable the feature, Zoom creates an automatic voiceprint during your meetings.
  • This voiceprint is a digital representation of your unique vocal patterns, used to isolate your voice and suppress other sounds.
  • The voiceprint is stored locally on your device and can be deleted at any time through your audio settings.

Optional Voiceprint Recording

• • For enhanced performance, users can make a short voice recording by reading a script provided by Zoom.
  • This reference voiceprint recording is analyzed by Zoom to refine the isolation process further, working alongside the automatic voiceprint.
  • Zoom stores this recording securely until you delete it in your audio settings.

Real-Time Noise Suppression

• • During meetings, the system uses the voiceprints to suppress background noise dynamically, prioritizing your speech for a clear and uninterrupted audio experience.

Who Can Use Personalized Audio Isolation?

• The feature is not available on:
  • Common Area devices (shared office devices or kiosks).
  • Older devices that don’t meet the system requirements.

To use Personalized Audio Isolation effectively, ensure your device meets the prerequisites.

How to Enable Personalized Audio Isolation

For Windows, macOS, and Linux Users:

1. Open the Zoom app and sign in.
2. Click your profile picture and select Settings.
3. Navigate to the Audio tab under Settings.
4. Under Audio Profile, select Personalized audio isolation.
5. A consent prompt will appear, explaining the creation of an automatic voiceprint during your meetings. Click OK to proceed.
6. Your voiceprint will be created automatically during the next meeting.

Optional: Creating a Voiceprint Recording

1. In the same Audio settings, select the option to Create Voiceprint Recording.
2. Follow the on-screen instructions to read a Zoom-provided script.
3. Save the recording for improved voice isolation during future meetings.

How to Delete Your Voiceprint

• Go to the Audio Settings in your Zoom app.
• Locate the voiceprint section and choose Delete Voiceprint Recording.
• Deleting this recording may reduce the effectiveness of noise isolation.
• If the system creates an automatic voiceprint, it generates a new one the next time you speak during a meeting unless you turn off the feature.

Why Personalized Audio Isolation Matters

Zoom’s Personalized Audio Isolation offers a significant upgrade from standard noise suppression by introducing tailored voice isolation. This ensures a distraction-free experience for users who work in challenging audio environments, such as open offices, shared households, or outdoor settings.

Use Cases

• Remote Work: Professional-grade audio clarity for virtual meetings.
• Online Education: Distraction-free virtual classrooms for teachers and students.
