Bodily gestures, facial expressions, and intonations are argued to be notably important features of spoken language which are opposed to written language. Bodily gestures with or without spoken words can influence the clarity and density of expres?sion and involvement of listeners. Facial expressions whether or not correspond with exact thought could be"decoded"to influence the extent of intelligibility of expression. Intonation can always reflect the mutual beliefs concerning the propositional content and states of consciousness relating to the expression and interpretation. Therefore, these can considerably improve or abate the accura?cy of expression and interpretation of thought.
