Operations are enabled individually by server configuration. Disabled operations return 503 without a task. Music credit deduction is currently disabled.

Using this operation

Submit your recording of the verification phrase using the task ID and phrase ID from the same sample upload.

1. Prepare the fields shown in the example below. Replace sample URLs and IDs with resources you can access.
1. Set model to suno_voice_create and place the parameters inside input. Submit once and save the returned task_id.
1. Query the saved task or receive its callback. A processing result is not a reason to submit the operation again.
Save result.voice_id. Check its availability through GET /api/v1/voices/{voice_id} before reuse.

Create task

Send model and input to the common task endpoint. callback_url is an optional top-level public HTTPS address. All resource IDs are APIstable IDs owned by your account. Music credit deduction is currently disabled.

{
  "model": "suno_voice_create",
  "input": {
    "voice_upload_task_id": "YOUR_UPLOAD_TASK_ID",
    "phrase_id": "YOUR_PHRASE_ID",
    "upload_url": "https://example.com/verification.wav"
  }
}

Acceptance response

HTTP 200 confirms acceptance, not completion. Query GET /api/v1/tasks/{task_id} until data.status is succeeded or failed. Read data.result only after success; a failed task has its error in data.message.

{
  "code": 200,
  "msg": "success",
  "data": {
    "task_id": "YOUR_TASK_ID"
  }
}

Parameter reference

Field	Type	Required	Description and limits
voice_upload_task_id	string	Yes	APIstable task ID returned by suno_voice_upload, bound to the same account. maxLength: 200
phrase_id	string	Yes	APIstable verification phrase ID, bound to the selected voice upload. maxLength: 200
upload_url	string	Yes	Public HTTPS audio URL on port 443, without URL credentials. Use MP3/WAV/FLAC/OGG/M4A/AAC with a readable audio track. See the operation size limit.
name	string	No / conditional	Voice or Persona display name. maxLength: 100
description	string	No / conditional	Voice or Persona description. maxLength: 1000

Inputs and limits

The schema lists supported fields, types and basic limits. Also follow Important conditions: cross-field and source-resource checks are not fully represented in JSON Schema. Unknown parameters are rejected. URL fields accept public HTTPS URLs, never file objects.

{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "type": "object",
  "properties": {
    "voice_upload_task_id": {
      "type": "string",
      "minLength": 1,
      "maxLength": 200,
      "description": "APIstable task ID returned by suno_voice_upload, bound to the same account."
    },
    "phrase_id": {
      "type": "string",
      "minLength": 1,
      "maxLength": 200,
      "description": "APIstable verification phrase ID, bound to the selected voice upload."
    },
    "upload_url": {
      "type": "string",
      "format": "uri",
      "description": "Public HTTPS audio URL on port 443, without URL credentials. Use MP3/WAV/FLAC/OGG/M4A/AAC with a readable audio track. See the operation size limit."
    },
    "name": {
      "type": "string",
      "maxLength": 100,
      "description": "Voice or Persona display name."
    },
    "description": {
      "type": "string",
      "maxLength": 1000,

    }
  },
  "required": [
    "voice_upload_task_id",
    "phrase_id",
    "upload_url"
  ],
  "additionalProperties": false
}

Important conditions

The sample session must be ready and unexpired, and phrase_id must belong to the same voice_upload_task_id. upload_url is your new recording reading the returned phrase. After the 24-hour sample session expires, restart from suno_voice_upload.
Audio URL inputs must contain readable MP3/WAV/FLAC/OGG/M4A/AAC audio with positive duration; the limit is 500 MiB per file. URLs must be publicly accessible HTTPS on port 443, without embedded credentials or private-network addresses. Keep them accessible until the task finishes.
Uploaded files last 24 hours, generated files 14 days and task details 30 days. Reused files keep their original expiry. Valid Voice/Persona identity mappings are separate from task-log cleanup. Download files you need to retain.

Result schema

The creation response is {code:200,msg:“success”,data:{task_id}}. Poll GET /api/v1/tasks/{task_id}. On success, data.result is an object matching the schema below; it is otherwise null. input remains a JSON string.

{
  "type": "object",
  "required": [
    "voice_id",
    "name",
    "description",
    "available"
  ],
  "properties": {
    "voice_id": {
      "type": "string"
    },
    "name": {

      "type": "string"
    },
    "available": {
