These technologies enable machines to respond correctly and reliably to human voices, and provide useful and valuable services. This paper gives an overview of major technological perspective and appreciation of the fundamental progress of speech recognition and gives overview technique developed in each stage of speech recognition and also summarize and compare different speech recognition systems and identify research topics and applications which are at the forefront of this exciting and challenging field.
