I am doin my research in this field and have found the formula for delta to be d=[c(t+1)-c(t-1)]/2 where c is the MFCC feature. But if its so then How to determine the delta features from MFCC? can someone please help me out with the matlab codes for it. I am doing my research in this field and have found the formula for delta to be d(t)=[c(t+1)-c(t-1)]/2 where c is the MFCC feature. But if its so then what is the value of d(0) and d(1).
