Overdub vs. Regenerate: Which Should You Use?

If using Overdub speeds up your audio too much, consider using Regenerate. Overdub is ideal for quick edits to specific words or phrases, while Regenerate is better for changing the entire delivery of speech. Remember, Regenerate refines existing audio without needing re-recording, making it perfect for adjusting tone and pacing.

Adjust and fine tune AI audio

Convert AI voice clips into audio 

AI generated audio works differently than recorded audio in the script. You can't adjust the word boundaries speed, or use a Timeline tool on sections of AI audio. You'll need to first convert the AI voice clip into audio that you can edit.  
  1. Hover over an AI audio clip in the Timeline at the bottom of your editor.
  2. Select convert to audio.
If you're only seeing the wordbar, you'll need to expand the Timeline.


Change clip speed

After converting an AI voice clip to audio, you can speed up or slow down the clips from the sidebar.

  1. In the timeline, select the clip you want to adjust.
  2. In the playback section of the Layer Panel, click and drag the speed value or type in a value.

These adjustments are different from adjusting your composition's playback speed:

  • Clip speed changes will be included when you publish or export your composition.
  • Playback speed does not affect your published or exported content and only changes the speed during playback within the Descript project.

Add fades

After converting AI voice clip to audio, You can quickly create audio fades and crossfades by dragging a transition handle in the Timeline.


You can also adjust and apply fades or crossfades by clicking on the transition handle of your clip.
