.net实现语音朗读(TTS)功能

首先，添加DotNetSpeech.dll引用，可以在这里直接下载，也可以参照这篇文章说的，在安装Speech SDK以后，在Common Files\Microsoft Shared\Speech\目录下面找到SAPI.dll，用Tlbimp.exe工具将该dll转换成.net平台下的Assembly---DotNetSpeech.dll。

然后，using DotNetSpeech;

朗读功能：

1.  
   using DotNetSpeech;
2.  
   using System;
3.  
   using System.Collections.Generic;
4.  
   using System.Linq;
5.  
   using System.Net;
6.  
   using System.Net.Http;
7.  
   using System.Web.Http;
8.  
   using System.Speech.Synthesis;
9.  
   using System.Speech;
10.  
     
11.  
    namespace MyProject
12.  
    {
13.  
    public class ValuesController : ApiController
14.  
    {
15.  
    public SpeechSynthesizer synth; //语音合成对象
16.  
     
17.  
    GET api/<controller>
18.  
    //public IEnumerable<string> Get()
19.  
    //{
20.  
    // return new string[] { "value1", "value2" };
21.  
    //}
22.  
     
23.  
    GET api/<controller>/5
24.  
    //public string Get(string cont)
25.  
    //{
26.  
    // return cont;
27.  
    //}
28.  
     
29.  
    POST api/<controller>
30.  
    //public void Post([FromBody] string value)
31.  
    //{
32.  
    //}
33.  
     
34.  
    PUT api/<controller>/5
35.  
    //public void Put(int id, [FromBody] string value)
36.  
    //{
37.  
    //}
38.  
     
39.  
    DELETE api/<controller>/5
40.  
    //public void Delete(int id)
41.  
    //{
42.  
    //}
43.  
     
44.  
    //[HttpPost]
45.  
    [HttpGet]
46.  
    public string ToCall(string cont)
47.  
    {
48.  
    //调用示例：http://192.168.6.195:8081/api/values/ToCall?cont=请，刘笑笑，李秀秀，导医台领结果吧
49.  
    //https://localhost:44399/api/values/ToCall?cont=请，刘笑笑，李秀秀，导医台领结果吧
50.  
     
51.  
     
52.  
    //SpeechVoiceSpeakFlags flags = SpeechVoiceSpeakFlags.SVSFlagsAsync;
53.  
    //SpVoice sp = new SpVoice();
54.  
    sp.Voice = sp.GetVoices(" name=Microsoft Simplified Chinese ", "").Item(0);
55.  
    //sp.Voice = sp.GetVoices(string.Empty, string.Empty).Item(0); //0选择默认的语音,
56.  
    //sp.Rate = 0;//语速
57.  
    //sp.Volume = 100;//音量
58.  
    //sp.Speak(cont, flags);
59.  
     
60.  
    synth = new SpeechSynthesizer();
61.  
    //使用 synth 设置朗读音量 [范围 0 ~ 100]
62.  
                synth.Volume = 100;
63.  
                //使用 synth 设置朗读频率 [范围 -10 ~ 10]
64.  
                synth.Rate = 0;
65.  
     
66.  
     
67.  
    synth.SelectVoice(synth.GetInstalledVoices()[0].VoiceInfo.Name);
68.  
    //synth.SelectVoice("Microsoft Lili");
69.  
                //Voice.Speak(ggg, SpFlags);
70.  
                synth.SpeakAsync(cont);
71.  
     
72.  
     
73.  
     
74.  
     
75.  
    return "12345";
76.  
     
77.  
    }
78.  
     
79.  
     
80.  
    [HttpGet]
81.  
    public string GetAll()
82.  
    {
83.  
    return "Success";
84.  
    }
85.  
     
86.  
     
87.  
     
88.  
    }
89.  
    }

注：SpeechVoiceSpeakFlags是语音朗读的风格; Voice中是语音类型(语言、男(女)声),有 Microsoft Simplified Chinese，Microsoft Mary(Sam,Mike)等,

也可以这样：voice.Voice = voice.GetVoices(string.Empty, string.Empty).Item(0); //0选择默认的语音,
1选择第二个语音;Rate指的是语速。

当然，你也可以在此不写，打开控制面板中的语音设置类型和语速

生成语音文件：

1.  
   using System;
2.  
   using System.Collections.Generic;
3.  
   using System.Linq;
4.  
   using System.Web;
5.  
   using System.Speech.Synthesis;
6.  
   using System.Collections.ObjectModel;
7.  
   using System.Web.Configuration;
8.  
   using DotNetSpeech;
9.  
   using Microsoft.Win32;
10.  
    using System.Windows.Forms;
11.  
    using System.Threading;
12.  
     
13.  
     
14.  
    SpeechVoiceSpeakFlags flags = SpeechVoiceSpeakFlags.SVSFlagsAsync;
15.  
    SpVoice sp = new SpVoice();
16.  
    //sp.Voice = sp.GetVoices(" name=Microsoft Simplified Chinese ", "").Item(0);
17.  
    sp.Voice = sp.GetVoices(string.Empty, string.Empty).Item(0); //0选择默认的语音,
18.  
    sp.Rate = 0;//语速
19.  
    sp.Speak(strCont, flags);
20.  
     
21.  
    System.Windows.Forms.SaveFileDialog dialog = new System.Windows.Forms.SaveFileDialog();
22.  
    dialog.Filter = " All files (*.*)|*.*|wav files (*.wav)|*.wav ";
23.  
    dialog.Title = " Save to a wave file ";
24.  
    dialog.FilterIndex = 2;
25.  
    dialog.RestoreDirectory = true;
26.  
    if (dialog.ShowDialog() == DialogResult.OK)
27.  
    {
28.  
    SpeechStreamFileMode spFileMode = SpeechStreamFileMode.SSFMCreateForWrite;
29.  
    SpFileStream spFileStream = new SpFileStream();
30.  
    spFileStream.Open(dialog.FileName, spFileMode, false);
31.  
    sp.AudioOutputStream = spFileStream;
32.  
    sp.Speak("文字转语音的内容", flags);
33.  
    sp.WaitUntilDone(Timeout.Infinite);
34.  
    spFileStream.Close();
35.  
    }

（在WinForm和Web中都适用）
