摘要：The Speech is most prominent & primary mode of Communication among human being. The communication among human computer interaction is called human computer interface. It is the study of speech signals and the processing of methods of the signals. The signals are usually processed in a digital representation. It is closely tied to Natural Language Processing (NLP) Example is SpeechToText Synthesis. Since even before the time of Alexander Graham Bell’s revolutionary invention, engineers and scientists have studied the phenomenon of speech communication with an eye on creating more efficient and effective systems of humantohuman and humantomachine communication. our goal is to provide a useful introduction to the wide range of important concepts that comprise the field of digital speech processing. Speech processing in an effort to provide a more efficient representation of the speech signal. Speech Processing is divided in to various categories such as Speech recognition, Speaker recognition, Speech coding, Voice Analysis, Speech Synthesis and Speech Enhancement. This paper is mainly discussed with Speech. Speech Recognition is the process of speaking words into the computer, and having text appear on the screen, or having the computer perform various functions, is one of the most exciting and potentialfilled technologies available for students with special needs.
