A distinction needs to be made between speech and language and for the purposes of this chapter relatively simple definitions, modified from Sheridan (1972), will suffice. Speech is the ability to produce spoken sounds or more systemised vocalisations to express verbal symbols or words. Language is a cognitive skill in which there is a symbolisation of ideas or concepts for the purposes of communication in a social context, the communication having both expressive and receptive components.
