Hi All,

Does anyone have a good link to the theory behind why DCT is used for
MFCC feature vectors?  What exactly is it about the DCT values of the
mel frequency spectrum that makes it so appealing for voice
recognition.  I understand it makes the values less sensitive to
frequency, but how is that so?

Thanks
Rael

Hey stupident. Everybody is already sick of your idiotic questions. Why 
don't you start with some ABC book on digital processing before 
venturing into the complicated matters of voice recognition?

nice to see you back in form, Vlad.

sorta was wondering where you were during the DFT periodicity debate.

Feel like a big man now?

And I will solve the problem I'm trying to solve, with or without your
useless comments.  I always do.

Sure. To start with, get down from the tree and try walking on the back 
paws.

You know, I feel a little sorry for you.  It's obvious you've been
bullied or abused at some point and now feel like you need to prove
yourself by name-calling people who are taking an interest in a
subject you know something about.  It doesn't make you look any
smarter, it just makes you look like someone who needs help.  I've met
people like you before.  You might know a lot, and you might even be
smart, but you will never be content until you start treating people
with respect, because no matter how much you know or how clever you
are they'll never respect YOU until you do.

You might try googling on the title of the thread. After a couple of
pages of hits from this thread itself, there are a number of
potentially useful hits in the top 100. I think some of the papers by
Rosell may be responsive.
