1、首先需要安装一些32位库
sudo apt-get install libx11-dev:i386 libx11-dev
sudo apt-get install g++-multilib
sudo apt-get install osspd
2.下载HTK src和samples，http://htk.eng.cam.ac.uk/（测试可行版本为3.4.1）
3.解压，进入解压后的文件夹
./configure --prefix=/to/path 改为自己想安装的位置；例如./configure --prefix=/home/abc/htk;
make all （make all -j8/-j4）
#for ubuntu 15.04 //Modify “HLMTools/Makefile, not “HTMTools/Makefile” or root “Makefile“.
#line 77: replace with: if [ ! -d $(bindir) -a X_ = X_yes ] ; then mkdir -p $(bindir) ; fi （或者将此行前面的空格删除，再按tab键对齐；）
make install
4、添加环境变量
sudo gedit /etc/profile
最后一行加入
export PATH="$PATH:/安装文件路径",例如export PATH="$PATH:/home/abc/htk/bin",
保存后source/etc/profile 使更改生效，
5，测试
cd ../samples/HTKDemo#test：
mkdir -p hmms/{tmp,hmm.{0,1,2,3}} proto acc test
perl runDemo configs/monPlainM1S1.dcf
结果为
