Convert recorded audio to AI speech

​

Convert recorded audio to AI speech

1. In the script editor, click Add speaker. If a label has already been applied, click the existing Speaker label for the recorded section you want to change.
2. Choose a Speaker:
   • Select a Speaker that already exists in the current project from the AI speakers list.
   • Or, create a new Speaker by choosing a color, name, voice, and optional avatar. Click Save.
3. Re-select the label, then click the arrow > to open the Speaker menu.
4. Click Convert to AI speech.
5. If there are multiple Speakers in your composition, choose whether to convert just this section or all places in the whole composition where that speaker label appears.
6. Click Generate AI speech to confirm. Descript generates the new voice and replaces your original script audio with the new voiceover track. Your video layer is moved into the layer lane with the original audio muted.

To convert a specific range instead of a whole section, select the script text, then choose Convert to AI speech from the hover menu.

Fix gaps in your video

Descript’s Convert to AI speech feature replaces your original audio with an AI voice, but doesn’t retime your video to match the new voiceover. This can sometimes cause a gap, or empty frames in your original video. A few ways you could address this:

• Use a freeze frame: Adjust the pacing of your new audio by pausing your video on a specific frame for a few seconds.
• Cover the gap with B-roll or an image: Create a new scene with B-roll of your own, or browse Descript’s media panel.
• Slow the clip down: Stretch out the visual by slowing down the clip speed.
• Insert gap clips: If the new voiceover is shorter than your original video, convert your script to a standard audio layer, then add a gap clip or adjust the word gaps between words in your script.
