SUNO allows us to create a new version of Persona-v2-vox: singer style, which differs from the old version and requires obtaining the vox_audio_id first. This document explains the integration method for creating the new version of Persona-v2-vox. First, we need to use the API to obtain the vox_audio_id parameter value. This API can accept multiple input parameters, such as audio_id, vocal_start, and vocal_end, which refer to the song ID and the selected time range. Here, the audio_id we input is 42599b24-fb14-4cd3-a444-e15ffde3661b. 
import requests

url = "https://api.acedata.cloud/suno/vox"

headers = {
    "accept": "application/json",
    "authorization": "Bearer {token}",
    "content-type": "application/json"
}

payload = {
    "audio_id": "42599b24-fb14-4cd3-a444-e15ffde3661b",
    "vocal_end": 30,
    "vocal_start": 20
}

response = requests.post(url, json=payload, headers=headers)
print(response.text)
The result is as follows: 
{
  "success": true,

        {

    }
  }
}
As we can see, the id field in data is the vox_audio_id we want, and then we go to the Persona API to create the new version of Persona-v2-vox: singer style, with the specific input as shown below: 
import requests

url = "https://api.acedata.cloud/suno/persona"

headers = {
    "accept": "application/json",
    "authorization": "Bearer {token}",
    "content-type": "application/json"
}

payload = {
    "name": "test",
    "audio_id": "42599b24-fb14-4cd3-a444-e15ffde3661b",
    "vocal_end": 30,
    "vocal_start": 20,
    "vox_audio_id": "24f0827e-5847-4011-b9b7-fc0b62032b65"
}

response = requests.post(url, json=payload, headers=headers)
print(response.text)
After the call, we get the following result: 
{
  "success": true,
  "task_id": "e04b06a1-ff61-48e2-9fcc-15284bd18481",
  "data": {
    "persona_id": "49bef16d-6a09-49d1-8c24-a81663698b98"
  }
}
Then we can create songs using the new version of Persona-v2-vox: singer style based on the persona_id value above, and the specific creation method is consistent with the Suno Song Generation API Integration Instructions. Finally, we can use the Suno Vox API to create songs in the new version of Persona-v2-vox: singer style.
