Optimizing Audio Settings for Best ASR Performance

Our Automatic Speech Recognition (ASR) model relies on the clarity and quality of the audio it receives. Zoom’s default audio settings are optimized for general voice communication. They often apply noise suppression, compression, and other enhancements that can inadvertently degrade audio quality for speech recognition purposes. By enabling "Original Sound", you ensure that the audio transmitted is as close to the original input as possible, which allows our ASR model to process and recognize speech more accurately.

To ensure optimal performance of our Automatic Speech Recognition (ASR) model during Zoom meetings, it is important to configure your audio settings correctly. Here are the steps to enable the "Original Sound" audio profile in Zoom:

1. Open Zoom and Sign In

• Launch the Zoom application on your computer.
• Sign in with your Zoom account credentials.

• Click on your profile picture or initials in the upper-right corner of the Zoom window.
• Select "Settings" from the dropdown menu.

3. Enable "Original Sound" Option

• Scroll down to the "Audio profile" section.
• Check the box labeled 'Original Sound for musicians'.
• Ensure that "Echo cancellation" is checked too.

4. Activate "Original Sound for musicians" During Meetings

• Start or join a Zoom meeting.
• In the upper-right corner of the meeting window, click the button labeled "Original Sound for musicians".
• Once enabled, the button should display "Original Sound for musicians:On".
  

5. Verify Audio Quality

• Speak and ensure your audio is clear and without significant background noise.
• Adjust your microphone position and volume if necessary.

• Microphone Placement
  Ensure your microphone is positioned close to your mouth but not directly in front of it to avoid plosive sounds (popping). A distance of 6-12 inches is generally optimal.

• Quiet Environment
  Try to minimize background noise as much as possible. Close windows, and doors, and avoid noisy appliances.

• Microphone Quality
  Use a high-quality microphone. External USB microphones generally provide better audio quality than built-in laptop microphones.

• Test and Adjust
  Before important meetings, test your audio settings. Use Zoom’s built-in audio testing tools to ensure your voice is clear and at the right volume.

Enabling "Original Sound" in Zoom can greatly enhance the performance of our ASR model by providing clearer and more accurate audio input. By following the steps outlined above, you can ensure that your speech is recognized more accurately, leading to a better overall experience with our platform.
