A novel method is projected in order to get a better speech perception for the hearing impaired people. The algorithm is developed to achieve a specific number of bands of the preferred speech material for dichotic presentation.These bands are obtained using a set of dyadic filters which gives sharp transitions between selected bands. For implementing this algorithm MATLAB software is used .At first by implementing the code eighteen bands of Constant Bandwidth, nineteen bands of 1/3 Octave bandwidths and eighteen bands of critical bandwidth using pair of complementary comb filters from the filter sets are obtained. Ten subjects of various age group participated for the listening test .The test material used for the testing purpose involves a set of 15 Vowel Consonant Vowel (VCV) context .The performed test outcome proves that the projected method is usefull for improving the recognition score and also reduces the response time.
