Download HTK

HTK can be downloaded either via HTTP or FTP. In either case you need to register and agree to the license to receive a username and password which allows you to download HTK.

HTK is available as a source distribution. To build HTK3 you must have a working ANSI C compiler and associated tools installed on your system. Ask your Systems Administrator if you are unsure whether you have these tools.

Documentation for the individual tools that make up HTK can be found in the HTKBook.
