Uniform Frequency Sub-Band filtering Approach for Marathi Alphabets Processing
Journal Title: Scholars Journal of Engineering and Technology - Year 2017, Vol 5, Issue 9
Abstract
Speech enhancement aims to improve speech quality by using various algorithms. The objective of enhancement is improvement in intelligibility using audio signal processing techniques. The choice of the filter-bank has a significant influence on the performance of such systems in terms of signal quality, computational complexity and signal delay. Accordingly, the filter-bank design has to fulfill different, partly conflicting requirements in dependence of the considered application. In this paper we tried to design Low Pass, High pass & band pass Filters to process Natural Spoken Marathi alphabets. We also processed Segmented & overlapped Alphabets to compare our algorithm performance. Major perspective to design filter bank is to select particular filter band to process respective vowel & consonant. Keywords:Frequency Sub band; Speech; Marathi; Uniform Filtering; Formant Frequency
