kaldi在mac下基本使用

############ kaldi安装:
通用的安装参考http://jrmeyer.github.io/asr/2016/01/26/Installing-Kaldi.html


需要python3.7.4

conda create -n kaldi python=3.7.4
conda activate kaldi

 brew install automake sox

MKL安装：

官网下载，注册学生，
https://registrationcenter-download.intel.com/akdlm/irc_nas/tec/17172/m_mkl_2020.4.301.dmg

然后去邮箱里链接下载

MKL就安装成功了

git clone https://github.com/kaldi-asr/kaldi
git branch -a
git checkout -b 5.4 remotes/origin/5.4

cd kaldi/tools
./extras/check_dependencies.sh

OK之后

其中Makefile 中的

tar --exclude '*NONE*html' -xmaf sctk-$(SCTK_GITHASH).tar.gz
去掉参数a
改成 tar --exclude '*NONE*html' -xmf sctk-$(SCTK_GITHASH).tar.gz

make 

不要 make -j8

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


继续再tools中

./extras/install_irstlm.sh

.././install-sh -c -d '/Users/haoning02/Desktop/iosapp/kaldi/tools/irstlm/include'
/usr/bin/install -c -m 644 cmd.h thpool.h dictionary.h gzfilebuf.h htable.h index.h lmContainer.h lmclass.h lmmacro.h lmtable.h lmInterpolation.h mempool.h mfstream.h n_gram.h ngramcache.h ngramtable.h timer.h util.h crc.h interplm.h linearlm.h mdiadapt.h mixture.h normcache.h shiftlm.h cplsa.h cswam.h doc.h '/Users/haoning02/Desktop/iosapp/kaldi/tools/irstlm/include'

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


在tools下
cd ../src

./configure
make depend
make

cd kaldi/egs/yesno/s5

wget http://www.openslr.org/resources/1/waves_yesno.tar.gz
tar xvf waves_yesno.tar.gz
./run.sh



#################error： 在5.4版本，kaldi/tools 下make报错

shorten_x.c:325:22: error: implicit declaration of function 'pcm2alaw' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
                    *writebufp++ = pcm2alaw( ulaw2pcm[data0[i]] );

是sph2pipe_v2.5 的问题

用这个补丁：

https://github.com/kaldi-asr/kaldi/pull/4285/files
sph2pipe.c加#include <unistd.h>

ulaw.h 加
uchar pcm2ulaw( short int sample );
uchar pcm2alaw( short int pcmval );


##########error：在5.4版本，kaldi/tools 下make报错  ， sctk-2.4.10 报错

align.c:933:15: error: implicit declaration of function 'getpid' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
    int pid = getpid();

需要把Makefile中的sctk每次强制解压注释掉

.PHONY: sctk
sctk: sctk-2.4.10-20151007-1312Z.tar.bz2
#   tar xojf sctk-2.4.10-20151007-1312Z.tar.bz2 || \
#      tar --exclude '*NONE*html' -xvojf sctk-2.4.10-20151007-1312Z.tar.bz2
    rm -rf sctk && ln -s sctk-2.4.10 sctk

再修改：
./sctk-2.4.10/src/sclite/align.c
加
#include <unistd.h>

pid_t getpid(void);
pid_t getppid(void)

#########
sclite.c:579:15: error: implicit declaration of function 'TEXT_set_lang_prof' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
                if (!TEXT_set_lang_prof(argv[opt+1]))

在 ./sctk-2.4.10/src/sclite/sctk.h

加
#include <unistd.h>
int TEXT_set_lang_prof(char *)；


sctkUnit.c:1156:6: error: implicit declaration of function 'TEXT_set_lang_prof' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
     TEXT_set_lang_prof("babel_turkish");


./sctk-2.4.10/src/sclite/sctkUnit.c

加
#include <unistd.h>
int TEXT_set_lang_prof(char *);

git checkout -b 5.4 remotes/origin/5.4
这个版本不行，编译完的kaldi-ios.a缺少
OnlineSilenceWeighting
SingleUtteranceNnet3DecoderTpl

grep -nR SingleUtteranceNnet3DecoderTpl *




git checkout -b new-slurm.pl remotes/origin/kkm/new-slurm.pl

但是这个没有

所以既要有FatalMessageLogger 又要有 SingleUtteranceNnet3DecoderTpl 的branch还要继续找


###########
精简版：
python3.7.4
git clone https://github.com/kaldi-asr/kaldi
git branch -a


git checkout -b new-slurm.pl remotes/origin/kkm/new-slurm.pl
cd kaldi/tools

./extras/check_dependencies.sh
make
解决各种不兼容问题，implicit declaration of function ，基本都是引入 #include <unistd.h> 加缺的声明就好了

./extras/install_irstlm.sh


cd ../src

./configure
make depend

如果本地运行用make
如果编译成ios的库用build-kaldi-ios.sh
这个脚本里面有make ，会编译成ios能用的kaldi-ios.a
