This paper presents robust feature extraction techniques for isolated word recognition under noisy conditions. The proposed hybrid feature extraction techniques are Bark Frequency Cepstral Coefficients (BFCC) and Weighted Average Mel-Frequency Cepstral Coefficient (WMFCC). Both methods are tested in various noisy environments using a single Gaussian Hidden Markov Model (HMM) based isolated digit recognition system. The results clearly indicates that WMFCC performed well compared to Mel-Frequency Cepstral Coefficient (MFCC) in noisy environment using NOISEX-92 database. © 2014 IEEE.
