ASR项目实战-构建Kaldi

准备工作

安装构建时依赖的基础软件

软件清单如下：

• bzip2

• python3

• automake

• libtool

• cmake

• gcc

• g++

• gfortran

• git

• subversion

不同平台安装软件的方式不同，比如可以使用yum或者apt-get等。

下载开源软件

软件清单如下：

• Libunwind

• glog

• OpenFST

• OpenBLAS

• Kaldi

按照一定的规则，将下载后的文件放在指定目录，如下是样例

opensrc
    glog
        glog-0.4.0.zip
    Libunwind
        libunwind-1.3.1-src.zip
    Kaldi
        kaldi-master.zip
    OpenFST
        openfst-1.6.7.tar.gz
    OpenBLAS
        OpenBLAS-0.3.6.tar.gzinstall
    usr
        local
            bin
            sbin
            include
            lib
            lib64
script
    build.sh

构建脚本

build.sh的内容，如下为样例：

注意事项

OpenFST自身实现一套日志系统，与glog集成时会报符号冲突。当前有用户在官网上提出类似的问题，但没有官方的答复。为了完整利用glog的能力，需要对OpenFST的实现做一定的修改。
修改点主要涉及如下几个文件：

• src/include/log.h，删除代码中相关的类和变量的定义。

  #include <fst/types.h>#include <fst/lock.h>using std::string;// 删除中间出现的代码#define ATTRIBUTE_DEPRECATED __attribute__((deprecated))#endif

• src/include/flags.h，在头部引入glog的头文件，增加如下代码：

  #include <fst/types.h>#include <fst/lock.h>#include "glog/logging.h"  // 引入glog的头文件using std::string;

• src/lib/flags.cc，删除同名的变量。

  // DEFINE_int32(v, 0, "verbosity level");
