如何获取到api返回的请求参数后在下面代码中增加unity进行播放音频的方法？下面代码只会获取到返回参数的页面信息并没有获取到音频的文件播放请完整示例下代码htmlheadmeta name=viewport content=width=device-widthstyle type=textcssfont-face font-family TencentSans; src urlchrome-e

在获取到API返回的请求参数后，可以通过Unity的AudioSource组件来播放音频。首先，你需要在GenshinTextToSpeech类中添加一个AudioSource的变量：

public AudioSource audioSource;

然后，在Speak方法中，在获取到音频后，将其赋值给AudioSource的clip属性，并调用Play方法播放音频：

if (speechRequest.responseCode == 200)
{
    AudioClip audioClip = DownloadHandlerAudioClip.GetContent(speechRequest);
    _callback(audioClip);

    // 播放音频
    audioSource.clip = audioClip;
    audioSource.Play();
}

最后，确保你在Unity编辑器中将GenshinTextToSpeech脚本组件的audioSource属性与一个AudioSource组件关联起来。

这样，当调用Speak方法时，它会获取到音频并使用AudioSource播放音频。完整的代码示例如下：

using System;
using System.Collections;
using System.Xml.Linq;
using UnityEngine;
using UnityEngine.Networking;

public class GenshinTextToSpeech : TTS
{

请注意，这里的代码假设你已经在Unity中正确设置了AudioSource组件，并将其与GenshinTextToSpeech脚本组件的audioSource属性关联起来。
