After mfcc you can go for vector quantization (Compute the euclidean distance) fix threshold based on the max. euclidean distance and detect the word.

A digital speech coder can be classified into two main categories, waveform coders and vocoders. Waveform coders employ algorithms to encode and decode speech signals so that the system output is an approximation to the input waveform. Vocoders encode speech signals by extracting a set of parameters that are digitized and transmitted to the receive
