After the program starts, select New Project in the launch window. Click the Add Media Files button and select the video you want to edit. The file will be added to the Timeline.

To speed up or slow down the audio, adjust the Speed slider. Move the slider to the right to make sound faster or to the left to make it slower. Note that when you change the audio speed, the video playback speed also changes.

If you want to fade the audio in or out, move the appropriate sliders to set the timing for fade effects.

To distort your voice, click Audio Effects and select the effect you want to use from the list. You can add echo, make your voice higher or lower, or even create a robotic voice effect.

Click the Export button to save the edited video. In the dialog box that opens, set the format for your video, enter the file name, and select the destination folder. After you’ve specified all the settings, click the Start button to save the file on your computer. Now you know how to change the voices of videos with Movavi Video Editor!
