The inherent advantage of speech communication due to its variability, convenience and speed along with our increasing requirements to communicate with machines has driven the attention of researchers towards mechanical recognition of speech. Technological advancements and improvements in the fundamental approaches have shown a successful transition from small vocabulary isolated word recognition to large vocabulary continuous speech recognition. Even after years of research and development the accuracy of automatic speech recognition remains one of the major challenges. Design of speech recognition system requires careful selection of feature extraction technique and modeling approach to cover the challenges faced due to variability of speech-speaker characteristic, storage space and processing speed requirements. In this paper an effort has been made to highlight the progress made so far for mechanizing the recognition of speech along with the major challenges in this field. Authors have also presented a brief description of voice enabled service for common people. The objective of this paper is to summarize some of the well known methods used at various stages of speech recognition system along with their benefits and limitations.
