服务器评测
因为同事工作需要 kaldi ，所以安装过程有点麻烦。在此记录一下折腾的过程。
OS：Ubuntu 12.04 （amd64）
kaldi的下载地址 http://svn.code.sf.net/p/kaldi/code/ 我这里下载的是 stable
svn co http://svn.code.sf.net/p/kaldi/code/stable kaldi-stable
“ 在编译之前需要改个 sph2pipe_v2.5.tar.gz 的下载地址，源码中的地址一直连接不上，无法下载，需要改成 sourceforge 的地址，奇怪的是其他包的地址都是 sourceforge的，为什么这个会是http://merlin.fit.vutbr.cz/kaldi/sph2pipe_v2.5.tar.gz ”
编辑 kaldi-stable/tools/Makefile 将最后面部分的sph2pipe 下载地址改成如下地址
sph2pipe_v2.5.tar.gz:
wget -T 10 -t 3 http://merlin.fit.vutbr.cz/kaldi/sph2pipe_v2.5.tar.gz
sph2pipe_v2.5.tar.gz:
wget -T 10 -t 3 http://sourceforge.net/projects/kaldi/files/sph2pipe_v2.5.tar.gz
地址修改完成后，可以进行 make 了
cd kaldi-stable/tools
make 会自动去下载相应软件包、然后解压等等操作，除非中间出错，否则不用干预
出错了。。。。。由于之前用不到 automake autoconf libtool 工具，在进行到 irstlm 这一步时出错了。。。安装刚才提到的三个软件 automake autoconf libtool
patching file src/lmtable.h
patching file src/interpolate-lm.cpp
touch irstlm/.patched
cd irstlm; \
(./regenerate-makefiles.sh || ./regenerate-makefiles.sh) && \
./configure –prefix `pwd`

安装依赖
aptitude install automake autoconf libtool -y
继续make。。。。
make clean
make -j4
cd ../src
./configure
make -j4

如果您需要 nnetbin 工具，那么您得下载这个版本的了….. -_-!!

*** WARNING: expf() seems to be slower than exp() on your machine. This is a known bug in old versions of glibc. Please consider updating glibc. ***
*** Kaldi will be configured to use exp() instead of expf() in base/kaldi-math.h Exp() routine for single-precision floats. ***
关于那个gblic的提示，不知道是不是一定要升级glibc。
