本文主要介绍了Ubuntu14.04环境下安装编译HTK语音识别工具库的过程。
1、下载HTK
HTK官网是:http://htk.eng.cam.ac.uk/，进入即可下载。
2、编译HTK
首先确保你已经安装了g++和libx11，
sudo apt-getinstall libx11-dev:i386
解压HTK工具包，进入ht文件夹下面
sudo tar xzf HTK-3.4.1.tar.gz
cd htk
然后输入下面一段代码：
sudo ./configure --prefix=/usr/local/
（这样安装好的文件即可存放在/usr/local目录下面）
出现下面一段提示：
setting
config.status: creating HTKLVRec/Makefile
config.status: WARNING: HTKLVRec/Makefile.inseems to ignore the --datarootdir setting
config.status: creating Makefile
config.status: WARNING: Makefile.inseems to ignore the --datarootdir setting
**************************************************
HTK is now ready to be built.
Type"make all"to build the HTK libraries
and tools.
Then"make install"toinstallthem.
The tools will be installedin/usr/local//bin
Build notes: Language Modelling tools will be
built. HDecode will not be built. You can build
it manually later by running 'makehdecode
install-hdecode'
**************************************************
按照上面提示中所说，接下来依次输入以下命令
sudo make all
sudo make install
sudo make hdecode install-hdecode
3、测试HTK
进入/usr/local/bin目录下面
cd /usr/local/bin
然后输入
HInit
若出现以下信息则表明安装成功：
USAGE: HInit [options] hmmFile trainFiles...
Option Default
-e f Set convergence factor epsilon 1.0E-4
-i N Set max iterations to N 20
-l s Set segment label to s none
-m N Set min segments needed 3
-n Update hmm (suppress uniform seg) off
-o fn Store new hmm definfn (name only) outDir/srcfn
-u mvwt Update m)eansv)ars w)ghts t)rans mvwt
-vf Set minimum variance to f 1.0E-2
-w f setmix wt/discprob floor to f 0.0
-A Printcommandline arguments off
-B Save HMMs/transformsas binary off
-C cf Set configfileto cf default
-D Display configuration variables off
-Ffmt Setsourcedataformattofmt as config
-Gfmt Setsourcelabelformattofmt as config
-H mmf Load HMM macrofilemmf
-I mlf Load master labelfilemlf
-Ldir Set input label (or net)dir current
-Mdir Dir to write HMM macro files current
-S f Set scriptfileto f none
-T N Set trace flags to N 0
-V Print version information off
4、运行htkDemo
首先解压htk-samples,进入HTKDemo文件夹中
tar xzf HTK-samples-3.4.1.tar.gz
cd samples
cd HTKDemo
然后依次输入以下命令：
mkdir-p hmms/{tmp,hmm.{0,1,2,3}} proto acctest
perl runDemo configs/monPlainM1S1.dcf
若出现以下信息，证明测试通过：
