Howard, i really appreciate your sharing and waiting for your favorable reply^^thanks..
HI, Lip. I am happy that the information is helpful to you. Unfortunately, I have a long time not to touch HTK and almost research material and books left at another place. I am sure that you can get result in phoneme level and you have to code some script or code to help to get it. Sorry about my late reply.
Happy to see your reply..thanks Howard ^^
However...if got any related information when you get it about this ..could you please send them to me..? we can contact each others through email..my email and msn is weelipchin@yahoo.com..happy to know you yup..

Hi Howard ...what you mean.. is it that i need to code the perl script or code myself(add code)?Or htk has this function in engine already..what i need to do is find out this script?
(Using perl script such as mkclscript in htktutorial directory?)
Hello, Lip.
I can't remember the demo code including process codes in the phoneme level. I think it's not.
That what I mean you may need to code to show the results and calculate the related information.
What I have is all from Internet. You will get more than me because I have not focus on this topic for a long while. :P
