feature extraction method

Started by paulgado June 11, 2003
i am an undergraduate working on a thesis for phoneme recognition
using discrete wavelet transform (DWT), i was wondering if anyone
could help me on what's the best method or algorithm to use for
feature extraction of a signal. I will use this method to extract
features so i can finish the templates i will use for my database.I
already pre-processed the signals using dynamic time warping, then
normalized them, then the next step will be feature extraction but i
don't know what algorithm (which is not too hard) to use. I am trying
standard deviation now and might consider other statistical-based
method such as mean, variance, etc. if anyone can help me it would
certainly be of big help or if you have an m-file of that algorithm
it would surely help.thanks!!!
