Managing Cloned Voices¶
Voice List¶
The voice list displays all cloned voices:
| Column | Description |
|---|---|
| Name | Voice name |
| Language | Voice language |
| Status | Active, Processing, or Deleted |
| Created | Creation date |
| Voice ID | Unique identifier |
Voice Actions¶
| Action | Description |
|---|---|

| Delete | Remove the voice (soft delete) |
Deleting Voices¶
Deleting a voice sets its status to “deleted” rather than removing it from the database. This prevents orphaned references in existing agent configurations.

- Select or create an agent
- Go to Channel → Phone
- In the Voice dropdown, select your cloned voice
- Save the agent configuration

Cloned voices are workspace-scoped. All team members in the same workspace can use voices created by any member.
