一. 源码下载

git clone https://github.com/kaldi-asr/kaldi.git kaldi-trunnk

将源码clone到了kaldi-trunnk文件夹中, 接下来的操作都是相对于kaldi-trunnk目录;

二. tool安装

2.1 检测依赖


cd kaldi-trunnk/tools/extras


./check_dependencies.sh: sox is not installed.
./check_dependencies.sh: we recommend that you run (our best guess):
 sudo apt-get install  sox
You should probably do: 
 sudo apt-get install libatlas3-base


sudo apt-get install  sox
sudo apt-get install libatlas3-base


./check_dependencies.sh: all OK.

2.2 编译tools


cd kaldi-trunnk/tools


touch sctk/.configured
cd sctk; \
make CC="gcc         " CXX="g++" all && make install && make doc
make[1]: Entering directory '/home/sourcelink/work/test/kaldi-trunnk/tools/sctk-2.4.10'
(mkdir -p bin)
(cd src; make all)
make[2]: Entering directory '/home/sourcelink/work/test/kaldi-trunnk/tools/sctk-2.4.10/src'
(cd asclite; make all)
make[3]: Entering directory '/home/sourcelink/work/test/kaldi-trunnk/tools/sctk-2.4.10/src/asclite'
(cd core; make all)
make[4]: Entering directory '/home/sourcelink/work/test/kaldi-trunnk/tools/sctk-2.4.10/src/asclite/core'


Warning: IRSTLM is not installed by default anymore. If you need IRSTLM
Warning: use the script extras/install_irstlm.sh
All done OK

结果中有个警告提示IRSTLM默认未安装, 安装情况详见2.3节;

2.3 IRSTLM 安装


cd kaldi-trunnk/tools/extras
****() Installing IRSTLM
****** You are trying to install IRSTLM from the wrong directory.  You should
****** go to tools/ and type extras/install_irstlm.sh.

这提示了一个错误, 按照提示执行:

cd kaldi-trunnk/tools


***() Installation of IRSTLM finished successfully
***() Please source the tools/extras/env.sh in your path.sh to enable it

根据它的log输出我并没有找到extras目录下找到env.h, 而是在tools目录下:



三. src安装

3.1 查看安装教程


These instructions are valid for UNIX-like systems (these steps have
been run on various Linux distributions; Darwin; Cygwin).  For native Windows
compilation, see ../windows/INSTALL.

You must first have completed the installation steps in ../tools/INSTALL
(compiling OpenFst; getting ATLAS and CLAPACK headers).

The installation instructions are

  ./configure --shared
  make depend -j 8
  make -j 8

Note that we added the "-j 8" to run in parallel because "make" takes a long
time.  8 jobs might be too many for a laptop or small desktop machine with not
many cores.

For more information, see documentation at http://kaldi-asr.org/doc/
and click on "The build process (how Kaldi is compiled)".

3.2 按部就班

编译原则: 核心*2

输入nproc命令, 查看核心数:


  ./configure --shared
  make depend -j8
  make -j8


.so /usr/lib/libatlas.so.3 /usr/lib/libf77blas.so.3 /usr/lib/libcblas.so.3 /usr/lib/liblapack_atlas.so.3 -Wl,-rpath=/usr/lib -lm -lpthread -ldl  -o lattice-lmrescore-kaldi-rnnlm-pruned
make[1]: Leaving directory '/home/sourcelink/work/test/kaldi-trunnk/src/latbin'
echo Done

3.3 测试cuda

cd kaldi-trunnk/src/cudamatrix
  • 修改makfile

makefile中的TESTFILES修改为BINFILES, 接着从新编译;

make clean
  • 测试

四. 验证

验证kaldi是否安装成功,可以选择运行 egs/ 目录下的许多测试用例脚本。

cd kaldi-trunnk/egs/yesno/s5
