# 歌词时间轴

> 取歌词逐句的时间轴与整首的波形数据，可用于逐句高亮和绘制音轨图。

> [!TIP]
>
> 也可以用统一任务接口 `POST /v1/task/submit` 提交：`model` 填 `suno/aligned-lyrics`，参数放进 `input`。两种写法效果与计费完全一样。

> [accordion] 任务结果
>
> 任务成功后，查询结果里产物的格式
>
> 任务成功后，结果放在 `data.result` 里：
>
> ```json theme={null}
> {
>   "code": "success",
>   "data": {
>     "task_id": "5adac6ee-...",
>     "action": "aligned-lyrics",
>     "model": "suno/aligned-lyrics",
>     "status": "SUCCESS",
>     "progress": "100%",
>     "result": {
>       "status": "complete",
>       "alignment": [
>         {
>           "word": "[Verse 1]\n雨打在铁皮屋顶上",
>           "start_s": 12.3,
>           "end_s": 15.8
>         }
>       ],
>       "waveform_data": [
>         0.12,
>         0.34,
>         "..."
>       ]
>     }
>   }
> }
> ```
>
> `result.alignment` 是逐句的歌词时间轴，每项带歌词与起止秒数；`result.waveform_data` 是整首的波形数据，可以用来画音轨图。
