各位大侠,小弟刚学c#.net,装了vs2005.
在下面的页面,看到关于语音识别的代码:
http://www.51cto.com/art/200509/4376_1.htm
于是,赶忙打开vs2005,新建一个工程,并添加了两个按钮button1和button2,还有一个textbox1.
把页面中的下列代码粘贴到工程中,并添加sapi.dll引用,using speechlib;如下:
namespace windowsapplication1
{
public class sprecognition
{
private static sprecognition _instance = null;
private speechlib.ispeechrecogrammar isrg;
private speechlib.spsharedrecocontextclass ssrcontex = null;
private system.windows.forms.control cdisplay;
private sprecognition（)
{
ssrcontex = new spsharedrecocontextclass（);
isrg = ssrcontex.creategrammar（1);
speechlib._ispeechrecocontextevents_recognitioneventhandler rechandle = new _ispeechrecocontextevents_recognitioneventhandler（contexrecognition);
ssrcontex.recognition += rechandle;
}
public void beginrec（control tbresult)
{
isrg.dictationsetstate（speechrulestate.sgdsactive);
cdisplay = tbresult;
}
public static sprecognition instance（)
{
if （_instance == null)
_instance = new sprecognition（);
return _instance;
}
public void closerec（)
{
isrg.dictationsetstate（speechrulestate.sgdsinactive);
}
private void contexrecognition（int iindex, object obj, speechlib.speechrecognitiontype type, speechlib.ispeechrecoresult result)
{
cdisplay.text += result.phraseinfo.gettext（0, -1, true);
}
}
public partial class form1 : form
{
public form1（)
{
initializecomponent（);
}
...
编译通过,无错误.现在的问题是:
我应该如何做,才能使点击button1按钮后,开始语音输入.
并在textbox1.text属性中显示语音输入的结果文字.
点击button2按钮,停止当前语音输入.
请问:要把public class sprecognition...代码段粘贴在工程的那个位置.
同时,如何在button1和button2中添加按钮事件语句呢,谢谢大家. |
