SUNO 允许我们对生成的音乐进行二次创作，获取音乐的歌词、音频时间线，本文档讲解相关 API 的对接方法。 该 API 只有一个输入参数，就是 audio_id，它是官方生成的歌曲ID。 这里我们输入的 audio_id 是 ec13e502-d043-4eb2-92ee-e900c6da69d1。 
import requests

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

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

payload = {
    "audio_id": "ec13e502-d043-4eb2-92ee-e900c6da69d1"
}

response = requests.post(url, json=payload, headers=headers)
print(response.text)
结果节选如下：

aligned_words 字段说明

可以看到，data.aligned_words 是对象数组，每个对象代表一个带有时间信息的词或短语。
  • word: 歌词中的实际词或短语
  • success: 布尔值，表示此词的对齐是否成功
  • start_s: 词的开始时间
  • end_s: 词的结束时间
  • p_align: 对齐的概率或置信度分数，范围为 0 到 1
