Installing HTK on Linux or Unix
Please note that from version 3.3, HTK uses
Autoconf to facilitate the installation process.
If you have a particular reason to install an older version of HTK (3.2.1 or
earlier), please refer to this
document.
Prerequisites
- A C compiler. All Linux distributions suitable for developers will have
a copy of gcc installed, but you can use other compilers such as the Intel
compiler icc. If in doubt, please ask your system administrator.
- For testing, you will require a Perl
Interpreter. Most modern Linux/Unix systems include one by default.
- You will need either tar and gzip (if you download the sources via ftp or
http) or CVS (if you download from our CVS server). These tools are usually
included by default with Linux distributions. Many other modern UNIX variants
also supply them, as optional packages if not by default.
- If compiling on Apple Macintosh OS X, you must have the XCode and XOrg-devel products installed. These are available for no cost from the Apple Developer Connection. Registration with Apple is required.
- Register on this site by accepting the HTK End User Licence Agreement,
then download the latest HTK source code.
- Some experience of working with one of the Unix shells (e.g. bash, csh,
tcsh). You will need to know which shell you are using, if unsure type:
> echo $SHELL
- You will also need to know how to edit files and how to set environment variables.
If you require assistance...
If you are unfamiliar with installing software from source on Linux or Unix,
you may resolve any queries more quickly and reliably if you ask a
knowledgeable colleague or your local technical support for assistance
in the first instance.
If that option is unavailable to you, please try the following sources of assistance:
- Search the archives of the htk-users mailing list
- If you don't find what you're looking for in the search, subscribe to the htk-users list and post your question there.
Compilation and installation
After unpacking the sources, cd to the htk-3.3 directory. Decide
where you wish the binaries to be installed (default is /usr/local
which will put the tools in /usr/local/bin.linux)
then type ./configure --prefix=/path/to/your/installation
Then running make all will build and install HTK.

Testing
Among the samples on the HTK website you'll find the HTK-samples package
that can be used to test your installation.
As an initial test of the installation please run the HTK
demonstration using the configuration file
HTKDemo/configs/monPlainM1S1.dcf. There is a README file in the
HTKDemo directory explaining the operation of the demonstration in
detail but, in short, you need to run the demonstration script passing
it the configuration file configs/monPlainM1S1.dcf as input.
To test the language modelling tools you should follow the tutorial
in the HTK book, using the files in the LMTutorial/ directory.
Before running the demo make sure you have compiled all the HTK tools
and the executables are in your PATH, i.e. just typing 'HInit' at the
commandline prints a short usage summary. To run the demonstration
type:
cd HTKDemo
perl runDemo.pl configs/monPlainM1S1.dcf
The recognition results obtained should match the following.
