The performance level of speech recognizer drops significantly when there is an acoustic mismatch between training and operational environments. A speech recognizer is called robust if it preserves good recognition accuracy even in the mismatch conditions. Present study addresses the recognition of English speech in noisy environments and presents the comparative study of various frequency scales used in parameterization based on the average recognition rate. For the robust automatic speech… CONTINUE READING
