kaldi安装

VM配置信息如下:

  • 系统—CentOS7

  • 内存—4G

  • 处理器—4×1

  • 硬盘—20G

  • 网络适配器—桥接模式

P.S 如需建立SSH连接需要配置/etc/sysconfig/network-scripts/ifcfg-ens33文件 “ONBOOT=yes”;

一、安装教程

➢步骤一：下载kaldi的文件

1
git clone https://github.com/kaldi-asr/kaldi.git

➢步骤二：查看安装指南文档

[root@localhost ~]# cd kaldi/
[root@localhost kaldi]# ls
cmake           COPYING  egs      misc       scripts  tools
CMakeLists.txt  docker   INSTALL  README.md  src      windows
[root@localhost kaldi]# cat INSTALL 
This is the official Kaldi INSTALL. Look also at INSTALL.md for the git mirror installation.
[Option 1 in the following does not apply to native Windows install, see windows/INSTALL or following Option 2]

Option 1 (bash + makefile):

  Steps:
    (1)
    go to tools/  and follow INSTALL instructions there.

    (2)
    go to src/ and follow INSTALL instructions there.

Option 2 (cmake):

    Go to cmake/ and follow INSTALL.md instructions there.
    Note, it may not be well tested and some features are missing currently.

➢步骤三：进入tools，根据指令执行编译

[root@localhost kaldi]# cd tools/
[root@localhost tools]# cat INSTALL 
To check the prerequisites for Kaldi, first run

  extras/check_dependencies.sh

and see if there are any system-level installations you need to do. Check the
output carefully. There are some things that will make your life a lot easier
if you fix them at this stage. If your system default C++ compiler is not
supported, you can do the check with another compiler by setting the CXX
environment variable, e.g.

  CXX=g++-4.8 extras/check_dependencies.sh

Then run

  make

which by default will install ATLAS headers, OpenFst, SCTK and sph2pipe.
OpenFst requires a relatively recent C++ compiler with C++11 support, e.g.
g++ >= 4.7, Apple clang >= 5.0 or LLVM clang >= 3.3. If your system default
compiler does not have adequate support for C++11, you can specify a C++11
compliant compiler as a command argument, e.g.

  make CXX=g++-4.8

If you have multiple CPUs and want to speed things up, you can do a parallel
build by supplying the "-j" option to make, e.g. to use 4 CPUs

  make -j 4

In extras/, there are also various scripts to install extra bits and pieces that
are used by individual example scripts.  If an example script needs you to run
one of those scripts, it will tell you what to do.

All done OK

➢步骤四：进入src，按照指令安装

[root@localhost kaldi]# cd src
[root@localhost src]# cat INSTALL 

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)".

[root@localhost kaldi]# cd src
[root@localhost src]# featbin/copy-feats
featbin/copy-feats 

Copy features [and possibly change format]
Usage: copy-feats [options] <feature-rspecifier> <feature-wspecifier>
or:   copy-feats [options] <feats-rxfilename> <feats-wxfilename>
e.g.: copy-feats ark:- ark,scp:foo.ark,foo.scp
 or: copy-feats ark:foo.ark ark,t:txt.ark
See also: copy-matrix, copy-feats-to-htk, copy-feats-to-sphinx, select-feats,
extract-feature-segments, subset-feats, subsample-feats, splice-feats, paste-feats,
concat-feats

Options:
  --binary                    : Binary-mode output (not relevant if writing to archive) (bool, default = true)
  --compress                  : If true, write output in compressed form(only currently supported for wxfilename, i.e. archive/script,output) (bool, default = false)
  --compression-method        : Only relevant if --compress=true; the method (1 through 7) to compress the matrix.  Search for CompressionMethod in src/matrix/compressed-matrix.h. (int, default = 1)
  --htk-in                    : Read input as HTK features (bool, default = false)
  --sphinx-in                 : Read input as Sphinx features (bool, default = false)
  --write-num-frames          : Wspecifier to write length in frames of each utterance. e.g. 'ark,t:utt2num_frames'.  Only applicable if writing tables, not when this program is writing individual files.  See also feat-to-len. (string, default = "")

Standard options:
  --config                    : Configuration file to read (this option may be repeated) (string, default = "")
  --help                      : Print out usage message (bool, default = false)
  --print-args                : Print the command line arguments (to stderr) (bool, default = true)
  --verbose                   : Verbose level (higher->more logging) (int, default = 0)

➢步骤六：VM拍个快照存档！

g++: fatal error: Killed signal terminated program cc1plus
compilation terminated.

这边建议是大于2G，越大越好，反正1G是跑不起来。

2.Tools/文件夹 make - j 4报错

建议分开编译安装

  • OpenFst

Kaldi使用FST作为状态图的表现形式，安装方式如下：

1
2
cd tools
make openfst
  • cub

cub是NVIDIA官方提供的CUDA核函数开发库，是目前Kaldi编译的必选工具，安装方式如下：

1
make cub
  • 安装三种语言模型

首先安装irstlm，执行

1
extras/install_irstlm.sh

下面安装srilm，执行：

1
sudo extras/install_srilm.sh
  • 进行编译
1
make -j 4

3.Ubuntu卡死

待解决~

三、Ubuntu22.04

2022.07.29更：最近新换了固态，装了个双系统，在双系统的Ubuntu上成功安装运行，看来是虚拟机性能不行。
