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。
