Download HTK 3.2.1

We need to use HTK release 3.2.1 because there are problems with Acoustic Model Adaptation using HTK release 3.3 (see Ticket #41 for details).

Step 1 - Register with HTK 

Step 2 - Download HTK Toolkit

• HTK version 3.2.1 source code (tar+gzip archive)

Step 3 - Compile & Install HTK

HTK consists of two libraries (built from the source code in HTKLib/ and HLMLib/) and a set of command line tools (in HTKTools/ and HLMTools/).  This Process assumes you are using Fedora Core.

1. Create a new folder for version 3.2.1 of HTK (something other than your HTK 3.3 release directory).  This tutorial will assume you are installing to this directory:

• /home/yourhomedirectory/htk-3.2.1 

2. Unpack your HTK distribution to the directory you just created.

3. Create a script called 'makeHTK.sh' in the root directory of HTK (i.e. /home/yourhomedirectory/htk-3.2.1) containing the following:

 

note: If you are using the 64bit distribution of Fedora, follow the instructions for creating you makeHTK script at this link).

Modify the HBIN variable in the above script to point to your install directory.

4. Set your permissions to allow execution of this script.

5. Create a directory called 'bin.linux' in your HBIN directory (this is where your HTK 3.2.1 executables will be created).

6. Execute this script as follows:

$./makeHTK.sh

Don't Update Your User Path

You should not update your user path (i.e. don't edit the .bash_profile in your home directory) to include HTK 3.2.1 binaries or libraries - this may cause conflicts with your currently installed copy of HTK3.3.
