For now, Overdub is only available in English.
To generate Overdub audio in a composition, you first need to link an Overdub voice to a speaker label. There are a couple of ways to do that:
- Select a speaker label and choose a speaker from the suggested list. It will include your custom voices (if you’ve created one) and Descript’s stock voices. When you select a speaker, you will see the speaker label with the associated Overdub voice.
- Select a speaker label and click to open the Edit speaker window. You can create speaker labels from here and link Overdub voices to the labels.
Once you’ve linked an Overdub voice to a speaker label and you’ve added the label to your composition, you can generate Overdub by:
- Replacing existing Script audio — select a portion of the Script and click on Overdub in the hover menu or hit the O key.
Descript may automatically generate and replace the words surrounding your selection when you replace existing audio. This happens when the audio you’re replacing blends in with surrounding audio (i.e., there is not a clear space between the words); you can always adjust the crossover point from the timeline.
- Generate new audio content — enable Write mode and start typing. Your Overdub should begin generating after a few moments.
If you do not have an Overdub voice linked to your speaker label, typing using the write tool will generate placeholder text.
