without needed information ???
there is not much .
1)

i am guessing this is it
http://htk.eng.cam.ac.uk/
3)
did you install every required program and source needed ???
this is a pay site so i do not have access
are you fallowing some " install guide "
from looking at the site this software looks to be about 10 years old
you might have a very hard time building it on a new OS
it is likely you will NEED the old gcc 3.3 compiler installed
but voice rec software should be built in to the os as part of the people with disabilities act
