A Custom Voice Clone is a saved voice you can reuse across multiple dubs — for example, your CEO's voice across every webinar, or a brand voice that should sound identical in every video you publish. It's different from the two voice options Dubly.AI uses by default:
Automatic cloning of the speaker in your source video. This happens fresh on each dub and matches whoever is speaking on screen.
Studio voices — high-quality, professionally trained voices you can pick from a list. Same voice, available to everyone. A Custom Voice Clone sits in between: a voice that's specifically yours, available across all your projects, that you don't have to recreate on every video.
When to use a Custom Voice Clone
You publish a series and want every episode to sound the same — even on segments where the source speaker is different.
You want to dub videos in a target language that the source speaker doesn't speak well enough to clone from.
You're producing voice-over-style content where the on-camera person isn't supposed to be the voice.
When automatic cloning is the better choice
One-off videos where matching the on-screen speaker is the goal.
Interviews, lectures, or any content where each speaker should keep their own voice.
Can I clone my own voice — or a colleague's?
Your own voice — yes, freely. It's your voice, so no extra permission is needed. A colleague's, employee's, or anyone else's voice — only with their explicit, written consent. Cloning someone's voice without their permission can also carry legal risk in some jurisdictions, so when in doubt, get their permission in writing first. For the full requirements — including what that written consent should cover — see our Acceptable use policy.
What you cannot clone
Public figures, celebrities, or politicians — without explicit signed consent, this is off-limits regardless of how good the source audio is.
A voice you sourced from social media or YouTube without the speaker's consent.
A voice from a dataset or recording where consent isn't documented.
How to set up a Custom Voice Clone
Custom Voice Clone setup is currently handled together with our team. Contact support and tell them:
Whose voice it is (and that you have permission to use it).
Where the voice should be used (single project, all your projects).
Sample audio of the voice if you have it. We'll configure it for your account so you can pick it as a target voice on any future dub.
