Transform your recordings into studio-quality audio in a few simple steps.

Enhance Speech helps make your recordings sound professional by removing background noise, balancing volume levels, and improving clarity. The resulting audio comes through clean and sharp, as if it were recorded in a studio or professional booth.

Learn about the supported file formats and the maximum file sizes and durations for uploading audio and video files here.

If multiple files are uploaded, select the video or audio from the list on the left.

The list displays the uploaded files and one of them is selected for speech enhancement.
Make a selection from the uploaded files to begin enhancing the speech.

Adjust the speech and background levels independently using the sliders located below the preview section:

  • Speech: Adjust the level of enhancement applied to isolated speech to make it clearer and more prominent. Moving the slider to the left reduces speech enhancement, making it less prominent. Moving it to the right increases enhancement, making the speech clearer and more distinct.
  • Background: Adjust the loudness of isolated background noise to make it quieter or louder as needed. Moving the slider to the left lowers the background noise volume, while moving it to the right raises it.
The Speech and Background sliders have adjustable levels, indicated by percentage values at each end for precise control.
Use the Speech and Background sliders to find the perfect mix of speech enhancement and noise reduction.

Toggle between the original and enhanced versions to compare before and after.
