unity调用android语音识别

语音识别在android下面很简单，因为语音识别就是google的嘛，呵呵~~~源代码网上也到处都有的，我当时试了一下google的语音识别，当时很慢，据说不够稳定，我又试了一下讯飞的语音识别，相对的确讯飞要快点，但是在调用他的mcs.jar包时，在eclipse运行正常，但是在unity调用的时候，我发现它的几个方法都能找到，但是不能调用，我也无语了，没办法就只能用google的技术了哦；而且都有3种方法哦，想详细了解就去这看看吧http://mysuperbaby.iteye.com/blog/1436754。我用了第三种方法，因为我不想显示那个对话窗口。我特别要谢谢雨松MOMO，雨松哥的那篇unity和android交互的文章很有用http://www.xuanyusong.com/archives/667。废话不对说了，我就贴一下android工程的代码和unity的代码，其他的你们参照雨松哥的那篇文章操作吧，呵呵~~~~
