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

C#调用科大讯飞离线语音合成实现文本转语音

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

Windows版

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。

调用样例

[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。

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。
