The objective of Speech Recognition is to determine the sequence of sound units from the Speech signal so that the linguistic message in the form of text to be decoded from the speech Signal. Speech is a sequence of sound units corresponding to a linguistic message. The main problem in these speech applications is processing of the speech signal in a manner similar to human auditory Processing mechanism, so that features relevant to a particular task can be extracted. This paper reviews some of the technologies used for speech recognition for different techniques and survey of some different recognition techniques.
