A Survey: Speech Recognition Approaches and Techniques

From many decades, people are working research in the area of voice recognition and communication. Researchers have valuable contribution in this area up to now. They have also contributed in the field of voice recognition as well as speaker dependent and speaker independent voice recognition. We have studied researcher's contribution and tried to provide a survey of scientific and an application view. In this paper we are going to present major scientific techniques and approaches, which have developed by various researchers in the broad field of voice recognition, that have developed from last few decades.
