Step by step
1. Open the Voices asset tab
From your workspace, open Brand Kit.

The Bevyl Voice Clone page opens with Upload Audio, Review, and Name Your Voice.

3. Add source audio

Each clone uses one source clip; uploading or recording again replaces it.
4. Review the generated voice
Click Next and keep the tab open while Bevyl builds the clone.
On Review your voice, play the sample. Click Sounds good to continue, or Try again to start over.
5. Name the voice
On Name your voice, enter a name your team will recognize.
Click Finish.
Bevyl returns you to Brand Kit; the new voice appears in the Voices list.
6. Adjust a saved custom voice
In the Voices list, click Adjust on a custom voice.
Drag Speed to slow or quicken the delivery, and Stability to trade variety for consistency. Click Save Voice to update the preview.
7. Rename or delete a saved custom voice
Click the voice name to rename it, then press Enter or click away to save.
To delete a voice, click the Delete voice trash icon and confirm Delete.
If something blocks you
Next is disabled: give it at least 10 seconds of clear audio.- The upload stalls: keep the file under 10 MB, or extract the audio from a large video first.
- The clone sounds wrong: click
Try again and provide a cleaner sample. - You cannot add another custom voice: self-service workspaces may be capped at one — delete an unused voice, upgrade, or contact support.
Done
The custom voice is saved in Brand Kit under Voices.
Next actions:
- Pick the voice when you create a project or regenerate a voiceover.
- Return here to rename, adjust, or delete it.
