$ sudo apt-get install libx11-dev
Go to HTK download page. But first, need to register (free) At this time, HTK version is 3.5 beta(2). Download both HTK source code and HDcode page.
$ tar xzf HTK-3.5.beta-2.tar.gz $ tar xzf HDecode-3.5.beta-1.tar.gz
Go to each of following folders: HTKLib, HLMLib, HTKTools, HLMTools, HTKLVRec and install like below:
$ cd HTKLib $ make -f MakefileCPU all $ make -f MakefileCPU install
(If you want to compile CPU using MKL or NVIDIA GPUs, change MakefileCPU according MakefileMKL, MakefileNVCC)
After run all install command, one directory is created under htk, named: bin.cpu. Need to set this directory as system-wide PATH. So, go to root directory and run:
$ sudo gedit /etc/environment
Add absolute path of bin.cpu directory in environment file and save it. Now, make change affect:
$ source /etc/environment
And check what we do is correct or not
$ echo $PATH
When Install HTK in step 2, there is also directory inside htk directory, named samples. If not, got to HTK download page to get it
$ cd samples
$ cd HTKDemo
$ mkdir -p hmms/{tmp,hmm.{0,1,2,3}} proto accs test
$ ./runDemo configs/monPlainM1S3.dcf
If test succeed, there is result like below:
