The easy way of communication between machine and human being is automatic speech recognition. Automatic speech recognition in different languages is one major research areas in signal processing field. Accuracy in SR is an important challenge in the research work. This paper discusses researches in the SR field in the past 60 years and gives an overview on SR process, types of speech, approaches, classifiers such as dynamic time warping (DTW), artificial neural network (ANN) etc. and also discusses various techniques for extraction of features like MFCCs, LPC, etc. which are used in speech recognition.Cite the ArticleAbhishek Dixit, Abhinav Vidwans, Anand Singh Bisen.
