Speech Recognition Algorithms And Architectures A Comparative Overview

Abstract

This paper presents a brief overview of the speech recognition technology. Algorithms such as Isolated Word Recognition, Dynamic Time Warping, Hidden Markov Modeling, Vector Quantization, Connected Word Recognition, and Continuous Speech Recognition are described. Research in this area is advancing mainly due to resurgence of commercial interest in this technology. Although there are a number of applications that could directly benefit by this technology, a key determinant of success or failure is the human interface. Much research still remains to be done to make this technology robust and usable in real-life applications. Some of these issues and the need for future research are outlined.
