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

Using this operation

Upload a voice sample and select a segment, then request a phrase, record verification, and check the created Voice.

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_upload 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.
After result.ready is true, pass result.voice_upload_task_id to the verification-phrase endpoint.

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_upload",
  "input": {
    "voice_url": "https://example.com/voice.wav",
    "vocal_start_s": 0,
    "vocal_end_s": 20
  }
}

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_url	string	Yes	Public HTTPS original voice recording: MP3/WAV/FLAC/OGG/M4A/AAC, up to 500 MiB, with a positive duration.
vocal_start_s	number	Yes	Selected vocal start in seconds, at most two decimal places. Use the original recording for Voice upload and the prepared vocal timeline for song Persona. min: 0
vocal_end_s	number	Yes	Selected vocal end in seconds, at most two decimal places; after start and within the audio. Song Voice Persona requires a 10–30 second range. min: 0
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_url": {
      "type": "string",
      "format": "uri",
      "description": "Public HTTPS original voice recording: MP3/WAV/FLAC/OGG/M4A/AAC, up to 500 MiB, with a positive duration."

  },
  "required": [
    "voice_url",
    "vocal_start_s",
    "vocal_end_s"
  ],
  "additionalProperties": false
}

Important conditions

Select 0 ≤ vocal_start_s < vocal_end_s ≤ the recording duration, with at most two decimal places. Wait for ready:true before requesting a phrase. The successful upload session lasts 24 hours.
Upload name/description are not automatically copied to the final Voice. Set them again in suno_voice_create if required.
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_upload_task_id",
    "ready"
  ],
  "properties": {
    "voice_upload_task_id": {
      "type": "string"
    },
    "ready": {
      "const": true
    }
