window speech实现语音控制

windows下利用微软的SpeechSDK实现语音控制                                                   

                           

语音识别是当前研究的热点，我们可以利用微软的语音识别引擎来进行二次开发。首先需要安装微软的SpeechSDK，安装完成后配置项目的包含目录和库目录,这些都不是重点，不会的可以去百度。然后就可以写代码了，码农嘛，还是看代码有感觉。

只有源文件还不行，程序中还用到一个XML格式的语音配置文件cmd.xml。如果是利用编译器调试程序，cmd.xml需要和源代码同目录；发布程序以后，cmd.xml就得放到程序可执行文件所在的目录下了。总之，程序必须访问到cmd.xml文件，方便起见，可以在两个目录下都放一个cmd.xml文件。

到这里，一个简单的语音控制程序Demo就算完成了，你对它说：“腾迅QQ”，它就打开了一个QQ，你说：“确定”,默认的QQ账号就自己登陆了。你还可以说：“音乐”,于是一首曼妙的音乐响起（为什么看不见播放器呢，因为在代码

设置了wmplayer.exe隐藏执行，想要关闭，嘻嘻，请打开任务管理器。另外，一定要设置你电脑上的音乐路径，不然你懂得）。

语音识别是不是挺有意思的，发挥你的想象，去震精别人吧。

语音识别是当前研究的热点，我们可以利用微软的语音识别引擎来进行二次开发。首先需要安装微软的SpeechSDK，安装完成后配置项目的包含目录和库目录,这些都不是重点，不会的可以去百度。然后就可以写代码了，码农嘛，还是看代码有感觉。

只有源文件还不行，程序中还用到一个XML格式的语音配置文件cmd.xml。如果是利用编译器调试程序，cmd.xml需要和源代码同目录；发布程序以后，cmd.xml就得放到程序可执行文件所在的目录下了。总之，程序必须访问到cmd.xml文件，方便起见，可以在两个目录下都放一个cmd.xml文件。
