Speech Recognition by using Optimization Method

In this paper we discuss the importance of speech recognition as well as we show how speech recognition evolved in last few years. Speech Recognition is a challenging domain, which made it an important research topic. In its early stage or at the time of invention it was not an as effective as it now, therefore many researchers worked on this domain and made it an exceptional one. This paper also shows the technological perspective and the progress in the field of speech communication. We also discuss how the speech recognition changed the way the world as it is now with the help of ASR (Automatics speech recognition) system work. Speech Recognition is based on the voice of research object. It allows the machine to turn speech signal into text as command. The speech recognition technology is gradually becoming the key technology of the IT man machine interface. The paper describes the development of speech recognition technology and its basic principles, methods, reviewed the classification of speech recognition systems and voice recognition technology. This paper gives you the complete idea about speech recognition.
