在.net中,对英文语音有较好的支持,但是对中文语音的支持还没有加入进来,我们要想实现中文发音或中文语音识别
,必需先安装微软的Speech Application SDK(SASDK),它的最新版本是 SAPI 5.1 他能够识别中、日、英三种语言,
你可以在这里下载:http://www.microsoft.com/speech/download/sdk51/,需要安装这两个文件Speech SDK 5.1和5.1 Language
Pack,其中5.1 Language Pack可以选择安装支持的语言。
安装好以后,我们就可以开始进行语音程序的开发了,当然,在这之前我们需要把SAPI.dll通过如下图所示添加
到引用中
下面我们设计一个能够朗读中英文混合语言的类:
我们将用单例模式实现该类,类的代码如下,我们将详细解释:
public class Speach
{
private static Speach _Instance = null ;
private SpeechLib.SpVoiceClass voice =null;
private Speach()
{
BuildSpeach() ;
}
![](/Images/OutliningIndicators/InBlock.gif)
public static Speach instance()
{
if (_Instance == null)
_Instance = new Speach() ;
return _Instance ;
}

{

Speak(strSpeak) ;
}

{

public void AnalyseSpeak(string strSpeak)
{
int iCbeg = 0 ;
int iEbeg = 0 ;
bool IsChina = true ;
for(int i=0;i<strSpeak.Length;i++)
{
char chr = strSpeak[i] ;
if (IsChina)
{
if (chr<=122&&chr>=65)
{
int iLen = i - iCbeg ;
string strValue = strSpeak.Substring(iCbeg,iLen) ;
SpeakChina(strValue) ;
iEbeg = i ;
IsChina = false ;
}
}
else
{
if (chr>122||chr<65)
{
int iLen = i - iEbeg ;
string strValue = strSpeak.Substring(iEbeg,iLen) ;
this.SpeakEnglishi(strValue) ;
iCbeg = i ;
IsChina = true ;
}
}
}//end for
if (IsChina)
{
int iLen = strSpeak.Length - iCbeg ;
string strValue = strSpeak.Substring(iCbeg,iLen) ;
SpeakChina(strValue) ;
}
else
{
int iLen = strSpeak.Length - iEbeg ;
string strValue = strSpeak.Substring(iEbeg,iLen) ;
SpeakEnglishi(strValue) ;
}
}

{

voice = new SpVoiceClass() ;
}
![](/Images/OutliningIndicators/InBlock.gif)
public int Volume
{
get
{
return voice.Volume ;
}
set
{
voice.SetVolume((ushort)(value)) ;
}
}
![](/Images/OutliningIndicators/InBlock.gif)
public int Rate
{
get
{
return voice.Rate ;
}
set
{
voice.SetRate(value) ;
}
}
![](/Images/OutliningIndicators/InBlock.gif)
private void Speak(string strSpeack)
{
try
{
voice.Speak(strSpeack,SpeechVoiceSpeakFlags.SVSFlagsAsync) ;
}
catch(Exception err)
{
throw(new Exception("发生一个错误:"+err.Message)) ;
}
}
![](/Images/OutliningIndicators/InBlock.gif)
public void Stop()
{
voice.Speak(string.Empty,SpeechLib.SpeechVoiceSpeakFlags.SVSFPurgeBeforeSpeak) ;
}

}
![](/Images/OutliningIndicators/InBlock.gif)
public void Continue()
{
voice.Resume() ;
}
![](/Images/OutliningIndicators/InBlock.gif)
}//end class
在 private SpeechLib.SpVoiceClass voice =null;这里,我们定义个一个用来发音的类,并且在第一次调用该
类时,对它用BuildSpeach方法进行了初始化。
我们还定义了两个属性Volume和Rate,能够设置音量和语速。
我们知道,SpVoiceClass 有一个Speak方法,我们发音主要就是给他传递一个字符串,它负责读出该字符
串,如下所示。
private void Speak(string strSpeack)
{
try
{
voice.Speak(strSpeack,SpeechVoiceSpeakFlags.SVSFlagsAsync) ;
}
catch(Exception err)
{
throw(new Exception("发生一个错误:"+err.Message)) ;
}
}
其中SpeechVoiceSpeakFlags.SVSFlagsAsync表示异步发音。
