Voice Digit Recognition Using Wavelets

Abstract

Wavelets are a familiar part of many types of digital signal processing, including compression, audio enhancement, image analysis, and voice recognition. They are an alternative method to Fourier Transforms. The purpose of this paper is to give the reader a sense of how a wavelet is used in voice recognition and what are the results. It will briefly describe what a wavelet is and how to use them in filtering. This paper will not go into great detail on the theory behind wavelets. For a more narrative approach to wavelets please refer to one of the references listed in section 6.1.
