how to apply bandpass filter to a .wav file

hi,

i have many .wav files belongs to (had,heed,whod,head,...etc)

i read these files and store it in a cell array,

i need to design a set of bandpass filters covering the signal bandwidth, and pass the vowel segment into each filter and compute the output.By, this i will get one output from each filter which represents the average power of the vowel in the filter band.These outputs are then used as feature vectors and a matching system to make the vowel recognizer.

can someone help me with this?

Use the bandpass function. For best results, also specify: 'ImpulseResponse','iir'
