因為同事工作需要 kaldi ，所以安裝過程有點麻煩。在此記錄一下折騰的過程。
OS：Ubuntu 12.04 （amd64）
kaldi的下載地址 http://svn.code.sf.net/p/kaldi/code/ 我這裡下載的是 stable
svn co http://svn.code.sf.net/p/kaldi/code/stable kaldi-stable
“ 在編譯之前需要改個 sph2pipe_v2.5.tar.gz 的下載地址，源碼中的地址一直連接不上，無法下載，需要改成 sourceforge 的地址，奇怪的是其他包的地址都是 sourceforge的，為什麼這個會是http://merlin.fit.vutbr.cz/kaldi/sph2pipe_v2.5.tar.gz ”
編輯 kaldi-stable/tools/Makefile 將最後面部分的sph2pipe 下載地址改成如下地址
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
地址修改完成後，可以進行 make 了
cd kaldi-stable/tools
make 會自動去下載相應軟件包、然後解壓等等操作，除非中間出錯，否則不用干預
出錯了。。。。。由於之前用不到 automake autoconf libtool 工具，在進行到 irstlm 這一步時出錯了。。。安裝剛才提到的三個軟件 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`

安裝依賴
aptitude install automake autoconf libtool -y
繼續make。。。。
make clean
make -j4
cd ../src
./configure
make -j4

如果您需要 nnetbin 工具，那麼您得下載這個版本的了..... -_-!!

*** 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. ***
關於那個gblic的提示，不知道是不是一定要升級glibc。
