If we take the first derivative of an MFCC feature, we can extract a Delta MFCC feature from it. In contrast to general MFCC features, Delta MFCC features can be used to represent temporal information.

In this case, we add an additional feature: x 3 = x 1 2 + x 2 2. After adding the additional feature, the logistic regression classifier works better. This example is more or less identical to the discussion here.
