Descript Overdub Voice Cloning

Descript recommends training the Overdub voice model with at least 10 minutes of clean recorded audio of your own voice, though more data generally produces more natural results. You must also read a specific consent statement to verify that you are cloning your own voice.

Overdub is designed primarily for short corrections, word replacements, and brief insertions within an existing audio track, where the synthetic voice blends naturally with your real recordings. Generating entire paragraphs or minutes of speech tends to expose artifacts and unnatural inflections that sound noticeably synthetic.

Descript's Overdub is integrated directly into its audio and video editing workspace, making it convenient for fixing specific words within a podcast or video project. ElevenLabs is a dedicated voice synthesis platform that produces more expressive and natural-sounding long-form speech but lacks Descript's integrated editing timeline.

Descript implements a consent verification step requiring the speaker to read a specific script before training a voice model, intended to prevent unauthorized cloning. However, like all voice cloning tools, it has raised broader ethical and legal questions about voice rights that the industry is still working to address.
