Voice management

Voice sharing

📘

Avatar and Voice sharing are only available on Synthesia's Enterprise plan.

📌

Note:

Avatars and voices are shared individually. Sharing an avatar does not automatically share the corresponding voice.

Go to the Voices page in your Synthesia account and find the voice you want to share.

To share it with a specific user, or several users:

1. Open up the 3-dot menu and select Share.
2. Type the names of the users you'd like to share it with in the Select users field, or click on the dropdown button for that field to find them in a list of workspace users.
3. Click the Share button next to the Select users field to share your voice.

To share it with the entire workspace:

1. Open up the 3-dot menu and select Share.
2. In the bottom-left of the Share menu, click on the Invite only dropdown.
3. Select the Shared with _Your Workspace Name_ option.

👍

You can return to the Share menu anytime to:

• Manage users your voice is shared with (add or remove access)
• Switch between sharing your voice with the entire workspace or with specific users

📌

Note:

• If the option to share your voice with the entire workspace is grayed out, your workspace admin has likely disabled this functionality. Contact them for further instructions.
• You can only share your voice within the workspace it exists it. If you need to share a voice with another workspace, contact Support ([email protected]) and provide them with:
  • The voice ID (via Copy ID in the options menu)
  • The workspace you'd like to create a copy of the voice in

How to revoke access to your voice

For a specific user:

1. Open up the 3-dot menu and select Share.
2. Find the user in the list of users and click on the Shared dropdown.
3. Select the Remove option.

For the entire workspace:

1. Open up the 3-dot menu and select Share.
2. In the bottom-left of the Share menu, click on the Shared with _Your Workspace Name_ dropdown.
3. Select the Invite only option.

🚧

Removing access doesn’t retroactively remove the voice from already-generated videos by other users.

They'll have to replace the voice in each video the voice has been used in, regenerate them, and republish them.

Permissions and notifications

• Voice owners can grant and revoke access at any time.
• If someone shares a voice with you, you’ll get:
  • An email notification.
  • An in-product notification.

How to rename a voice

Use the 3-dot menu on a voice and select Rename to give it a new name.

How to delete a voice

🚧

Deleting a voice will permanently delete it and all data associated with it. This action cannot be undone.

Deleting a voice will not remove it from any videos that have already been generated with it, but if you need to update and regenerate any of those videos, you'll have to replace the deleted voice.

Use the 3-dot menu on a voice and select the Delete option to delete it. You will be prompted to confirm this action before the voice is deleted.

Shared voices

You cannot delete voices that have been shared with you. Instead, you'll have to remove yourself from the list of users the voice has been shared with.

To remove your access to a shared voice:

1. Go to the Voices page in your Synthesia account.
2. Find the voice you want to remove your access from.
3. Open up the 3-dot menu and select Share.
4. Find your name in the list of users and click on the Shared dropdown.
5. Select the Remove option.
