Descript Overdub is an AI voice cloning and script-based audio editing feature integrated into the Descript all-in-one editing environment. Designed for podcasters, YouTubers, and video editors, Overdub allows creators to generate a digital clone of their own voice from a training script. Once trained, users can correct misspoken words in recorded audio or insert new dialogue simply by typing text into the transcript editor. Descript Overdub offers trial voice cloning on its free plan, enabling creators to experience text-based audio correction without re-recording full audio takes.
