# Delete a custom dubbing voice

> Permanently delete one of your saved custom dubbing voices. Catalog and other accounts’ voices cannot be deleted.

Permanently delete one of your saved custom dubbing voices. Catalog and other accounts’ voices cannot be deleted.

```http theme={null}
POST https://api.voicecheap.ai/v1/actions/dubbing_voices_delete
```

## Authentication and permissions

<ParamField header="x-api-key" type="string" required>
  Send a VoiceCheap API key in this header. Authorization: Bearer with the same API key is also supported. OAuth access tokens are accepted only by
  MCP, not by this REST endpoint.
</ParamField>

Required permissions: `voices:write`.

An active paid subscription is required. Permissions do not change team roles, resource ownership, media credits, or plan limits.

## Parameters

<ParamField body="requestId" type="string">
  Optional at the transport boundary: the server injects an identifier before validation when omitted. Supply your own stable UUID v4 to recover safely from a lost response.

  Format: "uuid". Pattern: `^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-4[0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}$`.
</ParamField>

<ParamField body="voiceId" type="string" required>
  Text value.

  Minimum length: 1. Maximum length: 255. Pattern: `^[A-Za-z0-9_-]+$`.
</ParamField>

<Accordion title="Complete input schema">
  The JSON Schema below preserves the exact field names, nested types, defaults, bounds, and accepted values exposed by discovery. Additional cross-field rules are listed in the operation notes.

  ```json theme={null}
  {
    "type": "object",
    "properties": {
      "requestId": {
        "type": "string",
        "format": "uuid",
        "pattern": "^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-4[0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}$",
        "description": "UUID v4 for this action. Reuse the same ID with identical arguments on retries."
      },
      "voiceId": {
        "type": "string",
        "minLength": 1,
        "maxLength": 255,
        "pattern": "^[A-Za-z0-9_-]+$"
      }
    },
    "required": ["voiceId"],
    "additionalProperties": false
  }
  ```
</Accordion>

## Idempotency

Use a UUID v4 in requestId or the Idempotency-Key HTTP header for each mutation. Reuse the same identifier and identical arguments after a network failure. If both are supplied, they must match. Replaying a saved request does not repeat the operation or charge another monthly call. Failed or interrupted requests are not restarted automatically.

Every mutation can return HTTP 202 when a retry finds the same request still running, even when its first execution is normally synchronous. If execution completed but resultStored is false, a retry returns HTTP 200 with saved request state instead of the original result. Retrieve the output through its domain history, result, or download action.

## Request examples

Replace example resource identifiers and media keys with values returned for your account. Keep the request identifier stable when retrying the same mutation.

<RequestExample>
  ```bash cURL theme={null}
  curl --request POST 'https://api.voicecheap.ai/v1/actions/dubbing_voices_delete' \
    --header "x-api-key: $VOICECHEAP_API_KEY" \
    --header 'Content-Type: application/json' \
    --data '{"requestId":"284a861a-4da8-4d67-ad48-8123e76c8e91","voiceId":"dubbing_voice_R8q3k9Yp"}'
  ```

  ```javascript JavaScript theme={null}
  const input = {
    requestId: '284a861a-4da8-4d67-ad48-8123e76c8e91',
    voiceId: 'dubbing_voice_R8q3k9Yp',
  };
  const response = await fetch('https://api.voicecheap.ai/v1/actions/dubbing_voices_delete', {
    method: 'POST',
    headers: {
      'x-api-key': process.env.VOICECHEAP_API_KEY,

  const body = await response.json();
  if (!response.ok) throw new Error(body.code + ': ' + body.message);
  console.log(body);
  ```

  ```python Python theme={null}
  import os
  import requests

  response = requests.post(
      "https://api.voicecheap.ai/v1/actions/dubbing_voices_delete",
      headers={"x-api-key": os.environ["VOICECHEAP_API_KEY"]},

      timeout=120,
  )
  body = response.json()
  if not response.ok:
      raise RuntimeError(f"{body.get('code')}: {body.get('message')}")
  print(body)
  ```
</RequestExample>

## Response

This operation returns HTTP 202 while running. Save requestId and poll action\_request\_get with that identifier and the original operation name. Polling states are running, completed, failed, and interrupted. A completed result can point to a separate media job; continue with the operation-specific status or output action.

Confirmation message after deleting the owned saved custom dubbing voice.

## Result fields

| Field | Description |
| - | - |
| `data.message` | Voice deleted after the custom dubbing voice has been removed. |

## Recover and poll this request

Use the same identifier even after a lost connection. If resultStored is false, retrieve the output through the corresponding history, result, or download action. Never start a second generation merely to check progress.

```bash theme={null}
curl --request POST 'https://api.voicecheap.ai/v1/actions/action_request_get' \
  --header "x-api-key: $VOICECHEAP_API_KEY" \
  --header 'Content-Type: application/json' \
  --data '{"requestId":"284a861a-4da8-4d67-ad48-8123e76c8e91","operation":"dubbing_voices_delete"}'
```

```json HTTP 200 theme={null}
{
  "data": {
    "requestId": "284a861a-4da8-4d67-ad48-8123e76c8e91",
    "operation": "dubbing_voices_delete",
    "status": "completed",
    "createdAt": 1792144800000,
    "updatedAt": 1792144820000,
    "resultStored": true,
    "result": {
      "message": "Voice deleted"
    }
  }
}
```

## Operation notes

* Use a UUID v4 requestId for this mutation and reuse it with identical arguments when retrying. Long-running actions first return a running request; this example is the completed handler result available from action\_request\_get.
* This mutation is destructive. Use the opaque custom voiceId from dubbing\_voices\_list; catalog and other accounts’ voices cannot be deleted.
* The response contains a message only. Call dubbing\_voices\_list to refresh saved-slot usage.
* Retry with the same requestId to recover the saved result. A new deletion request for a voice that has already been removed can return DUBBING\_VOICE\_NOT\_FOUND.
* Speech history and custom voices belong to the authenticated account. Team billing does not grant access to another member’s speech or voices.

## Usage

Each successful invocation consumes one monthly API/MCP call. Media credits and the operation's own generation allowances also apply.

| 503 | `SERVER_RESTARTING` | The server is restarting. Retry shortly and keep the same request identifier for a mutation. |
