Abstract
The computer has invaded all walks of life of human beings. Speech Pathology is no exception to this. The computer has been used extensively for Speech analysis
and synthesis for the diagnosis and treatment of speech disorders. However, speech recognition has not been used well for the purpose of speech and
language therapy, even though it has lot of potentials in terms of providing reinforcement to the cases, motivation and drill to the cases. Presently some
of the attempts have been made to use this for articulation testing and therapy. In this context, it was necessary to review the literature regarding speech
recognition and also study possible variables affecting speech recognition. Therefore, this is part of a proposed extensive study on application of speech
recognition in speech therapy and diagnosis.
