C/C++ Code Examples with HTK (Hidden Markov Toolkit)

Question

I am trying to get started with HTK, I grabbed a copy, compiled it, grabbed the book, and all went more or less fine, little troubles here and there but nothing serious.

Now after reading the book and googling quite a while, I do not see any documentation for the essential part for me: HTKLib. Everything is described into the smallest detail for all HTK tool programs (scriptable command line interface tools) but I cannot find a single example or tutorial how to actually call the lib.

Could anyone point me into a direction? The source code for the respective tools is included, but it would be rather cumbersome to have to extract the information for a reputable library by reading the source code... I would have expected a little more documentation , but maybe I simply overlooked it?

Any help is deeply appreciated,

Tom

edit: I was trying to use HTK for computer vision purposes, not for NLP, and for that I required that I could link against it, and call it from within my code. Thanks for your replies.

Answer 1

Maybe ATK is more suitable for you. Here is the explantation from the ATK site:

"ATK is an API designed to facilitate building experimental applications for HTK. It consists of a C++ layer sitting on top of the standard HTK libraries."

In addition Microsoft Research has another research tool here for training acoustic models. This includes a set visual project for HTKlib and a set of C++ HTK wrappers, but it may only include a subset of the HTK functionality and has licence restrictions.

Answer 2

I have not used it but use I the language modeling toolkit. I think the main intention is to use the command line tools provided. I imagine they are very flexible tools that will enable you to build and test models. Why do you want to use the code?

Also what are you trying to do?
