Audioseg-1.2.2是个非常强大的说话人分割的工具，里面包括常用的BIC、GMM模型和HMM模型三种常见的方法。本次只是讲解安装过程，详细的使用在今后调通后将详细的介绍。
安装前准备（据说spro,sphere,gsl三个有安装先后关系，需要依次安装gsl、spro、sphere、audioseg，在本次安装中我没注意这个问题）：
系统： & & & & & & & & & & Ubuntu14.04
gcc-version: & & & & & 4.8.2
Spro: & & & & & & & & & & & spro5.0
Sphere: & & & & & & & & &sphere2.7
gsl: & & & & & & & & & & & & &gsl1.16
首先，从官网上下载整个安装包和说明文档（https://gforge.inria.fr/frs/?group_id=533）
接着，将安装包解压，直接tar& -zxvf&& 压缩文件名.tar.gz
下一步，在解压后的根目录中，执行configure，注意一般需要添加前面三个软件的安装目录
./configure --with-spro=/usr/local --with-gsl=/usr/local --with-sphere=/home/xxx/nist下一步，按照说明文档只需要make一下即可，但在安装中出现如下问题：
显示无法找到lsp包 。于是从网上找相关的解决办法，发现系统里面没有liasp.so这个包（详见/os/356.html）
于是在度娘上查下这个包，原来它的名字是libsp1-dev，接着apt-get install即可完成安装包，重新查找后发现可以找到libsp.so这个包。
于是重新执行上面的步骤，出现找不到sqrt，math这些函数的问题，这个问题在linux挺常见，直接在Makefile的语句中将-lm放在该语句的最后即可。
下一步，make check
最后，make install完成安装，分别检查几个编译文件，能正常运行。
后记，在修改Makefile文件中，碰到无论怎么样修改Makefile，make真正执行的都不变这个问题，在网上查Makefile才明白整个过程，相信看到下面的图都能理解>> audioSeg.m
