public Form1()
{
InitializeComponent();

myPtr = GetForegroundWindow();
SRE.SetInputToDefaultAudioDevice(); // <=======默认的语音输入设备，你可以设定为去识别一个WAV文件。
GrammarBuilder GB = new GrammarBuilder();
//GB.Append("选择");
GB.Append(new Choices(new string[] { "红色", "绿色","开始" }));
Grammar G = new Grammar(GB);
G.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(G_SpeechRecognized);
SRE.LoadGrammar(G);
SRE.RecognizeAsync(RecognizeMode.Multiple); //<=======异步调用识别引擎，允许多次识别（否则程序只响应你的一句话）
}
void G_SpeechRecognized(object sender, SpeechRecognizedEventArgs e) {
//Text = e.Result.Text;

//MessageBox.Show(e.Result.Text);
switch (e.Result.Text) {
case "红色":
BackColor = Color.Red;
break;
case "绿色":
BackColor = Color.Green; //窗口颜色变为红色
break;
case "开始":
new Play().plays();//启动音乐播放（但是音乐不能播放出来！）求解答
break;
}
}
class Play {

[DllImport("winmm.dll")]
public static extern uint mciSendString(string lpstrCommand,
string lpstrReturnString, uint uReturnLength, uint hWndCallback);

public void plays() {

//MessageBox.Show("fsdfsdffds");
//System.Diagnostics.Process.Start(@"F:\Program Files\Tencent\QQ\Bin\QQ.exe");

mciSendString(@"close temp_alias", null, 0, 0);
mciSendString(@"open D:\KwDownload\song\林俊杰-她说.wma alias temp_alias", null, 0, 0);
mciSendString("play temp_alias repeat", null, 0, 0);
//MessageBox.Show("fsdfsdffds");

}

}
