在Unity中实现语音合成（TTS）webapi
在Unity中使用科大讯飞语音合成webapi实现语音合成

最重要的就这两个脚本了，可以直接复制使用！至于怎么控制播放大家可以自由控制，不过建议在调用StartTTS时，需要等待，否则会出错！下面我再给大家一个调用示例吧！
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;
using Webiat;
public TTSCore TTSCore;//把上面写的TTSCore脚本挂到场景物体中记得赋值哦
public AudioSource _ttsTalkAudioSource;//不要忘记赋值哦
public async void TTSPlay()
{
await TTSCore.StartTTS(resTxt, _ttsTalkAudioSource);
_ttsTalkAudioSource.Play();
}
//如果你还想播放完之后回调其他方法的话，你可以参考下面个
public async void TTSPlay(Action action=null)
{
await TTSCore.StartTTS(resTxt, _ttsTalkAudioSource);
_ttsTalkAudioSource.Play();
if (action==null)
return;
float clipLength = _ttsTalkAudioSource.clip.length;
Debug.Log("合成音频时长："+clipLength);
//下列两种延时调用都可用，不过个人建议使用第二种。需要注意的是第二种的参数单位是ms（毫秒），而第一种是s（秒）
//1、开启协程，延时调用action委托，此延时调用方法我已放到下边
StartCoroutine(DelayToInvoke.DelayToInvokeDo(() =>
{
action?.Invoke();
},clipLength));
//2、异步等待
//await Task.Delay(clipLength*1000);
//action?.Invoke();
}
using UnityEngine;
using System.Collections;
using System;
public class DelayToInvoke : MonoBehaviour
{
public static IEnumerator DelayToInvokeDo(Action action, float delaySeconds)
{
yield return new WaitForSeconds(delaySeconds);
action();
}
}
