WebSep 5, 2014 · GFCC features have shown best recognition efficiency for clean as well as for noisy database. GFCC and GF-PLP features are calculated using Matlab and saved in HTK format. Training and testing for speech recognition is done using HTK. The above-mentioned techniques were tested with impulsive signals within AURORA databases. WebThe gammawarp filterbank offers a substantial improvement in execution speed compared to previous dcGC implementations; for a dcGC filterbank, the gammawarp implementation is 24 to 38 times faster than the dcGC Matlab code of Irino.
