首先要安装SpeechSDK5.1 开发包和SpeechSDK5.1 Langague Pack（中英文） 语言包，不过VS2010里是自带SpeechSDK5.0的com组件的，也可以用。

	 简单讲一下四个方法：

	朗读时，使用

	复制代码 代码如下:

	

	voice.Speak(string,SpeechVoiceSpeakFlags.SVSFlagsAsync);


暂停，使用


	复制代码 代码如下:

	

	voice.Pause();


从暂停中继续刚才的朗读，使用


	复制代码 代码如下:

	

	voice.Resume();


停止功能


	复制代码 代码如下:

	

	voice.Speak(string.Empty, SpeechVoiceSpeakFlags.SVSFPurgeBeforeSpeak);


这样就可以完整地实现了“朗读”、“暂停”、“继续”、“停止”的功能。


	 

	下面就直接给出实例代码：

	复制代码 代码如下:

	

	 private void button1_Click(object sender, EventArgs e)

	        {

	            Analyse(this.textBox1.Text);

	        }
	

		 
	

		 
	

		public void Analyse(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 (Convert.ToInt32(chr) <= 122 && Convert.ToInt32(chr) >= 65)

		                    {

		                        int iLen = i - iCbeg;

		                        string strValue =

		             strSpeak.Substring(iCbeg, iLen);

		                        SpeakChina(strValue);

		                        iEbeg = i;

		                        IsChina = false;

		                    }

		                }

		                else

		                {

		                    if (Convert.ToInt32(chr) > 122 || Convert.ToInt32(chr) < 65)

		                    {

		                        int iLen = i - iEbeg;

		                        string strValue =

		strSpeak.Substring(iEbeg, iLen);

		                        iCbeg = i;

		                        IsChina = true;

		                    }

		                }

		            }
	

		             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);

		             }
	

		

		

		        }

		        private void SpeakChina(string speak)

		        }

		                         Voice.AudioOutputStream = SpFileStream;

		                         Voice.WaitUntilDone(100);
