Abstract:

This paper introduces the basics of HTK, a toolkit to build graphical user interfaces in Haskell. HTK is an encapsulation of Tcl/Tk [4, 7], but we will not assume any previous knowledge of Tcl/Tk. The article is meant as a rough guide and introduction to the structure of HTK. It is not meant as a complete reference manual; Rather, it should give readers enough information and background to get them started on their first HTKprograms, to know which parts of HTKmight be potentially useful in the applications they have in mind, what is feasible to build with HTK, and finally to enable them to find further information quickly in the reference material.
