To run this sample you must have a sound card connected to the PC. If you want to see some signal you must plug a Microphone to the mic connector of the sound card. If you don t have a mic you can plug an hearphone to the mic connector and speak closely in it.

采用期望最大算法最优化初始高斯混合模型的程序，笔者借用ubm自适应方法，很好的解决了模型不收敛的问题。-expectations largest algorithm using optimization initial Gaussian mixture model procedures, the author borrowed ubm adaptive method, a good model is not the solution convergence problem.

一个声音采样率转换的软件，可以实现不同采样率之间的转换，效果非常好。-A voice sample rate conversion software, can be achieved between different sample rate conversion, the effect was very good.
