C#文本转语音(科大讯飞离线版)
引言
文本转语音(Text To Speech)，简称TTS，在很多业务场景会用到，比如广播大厅，人机互动等。C#要实现TTS有不少选择，比如调用System.Speech，此处就不细说了，下面主要介绍一下C#调用科大讯飞的离线语音合成SDK来实现文本转语音。
产品介绍
地址：[https://www.xfyun.cn/service/offline_tts]
步骤
一、创建科大讯飞应用
进入科大讯飞控制台创建一个应用：[https://console.xfyun.cn/app/myapp]，没有账号的可以先注册一个。
创建应用后会有一个APPID，先记下来，后面写代码会用到。
二、下载对应平台的SDK
点击刚创建的应用，进去应用服务界面，在左侧点击语音合成下面的离线语音合成(普通版/高品质版)，如下
如果是windows平台，那么只能选择普通版。Linux的话可以选择高品质版，两者的效果在我看来相差还是比较大的。
下载完解压出来，目录如下
里面我们需要用到的是bin目录内的文件，当然你也可以参考samples里面的c语言代码，跟后面我提供的C#代码差不多
三、编写C#代码

上面分别是Windows的普通版与Linux高品质版的调用代码，比较凌乱，用的时候可以再封装一下，还要记得把之前记下来的APPID填到代码里。
四、调用
[ApiController]
[Route("[controller]")]
public class TextToSpeechController : ControllerBase
{
[HttpGet]
public FileStreamResult GetWav(string text,string speaker)
{
var fileName = Guid.NewGuid().ToString() + ".wav";
var mimeType = "application/....";
if(string.IsNullOrEmpty(speaker))
speaker = "xiaofeng";
if(RuntimeInformation.IsOSPlatform(OSPlatform.Linux))
LinuxXFTTSUtils.GetAudio(text, fileName, speaker, 50);
else if(RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
WindowsXFTTSUtils.GetAudio(text, fileName, speaker, 50);
Stream stream = System.IO.File.OpenRead(fileName);
System.IO.File.Delete(fileName);
return new FileStreamResult(stream, mimeType)
{
FileDownloadName = fileName
};
}
}
注意需要把下载的SDK包里面的bin目录内的文件拷贝到运行目录，如果是linux版，需要从libs里面拷贝libmsc.so库，speaker可以填xiaofeng或者xiaoyan，分别是男女声，需要更多的发音人可以去购买。文章来源：https://www.toymoban.com/news/detail-664116.html
代码基本完整提供了，各位直接复制粘贴使用即可，离线SDK可以免费体验30天，过期了需要购买或者重新注册创建新应用来延续使用。不过既然都是离线版了，直接把电脑时间固定住应该也能继续白嫖。哈哈，个人学习使用的话可以，商用版还是要购买噢。文章来源地址https://www.toymoban.com/news/detail-664116.html
