Speech Feature Extraction and Classification: A Comparative Review

This paper gives a brief survey on speech recognition and presents an overview for various techniques used at various stages of speech recognition systems. Researchers has been working in this research area for many years however accuracy for speech recognition still attention for variation of context, speaker’s variability, environment conditions .The development of speech recognition system requires certain concepts to be included-Defining different classes of speech, techniques for speech feature extraction, speech classification modeling and measuring system performance .The main aim of this paper is to discuss and compare different approaches used for feature extraction and classification stages in speech recognition system.
