Paralanguage refers to  the vocal aspect of communication. Vocal elements of language differ from verbal elements in this way: vocal elements involve sound and its manipulation for certain desired or undesired effects. Verbal elements are the particular words we choose when speaking. Thus, in saying "hello," the verbal aspect is the actual word "hello." The vocal aspect, or paralinguistic element, is the sound of the word when uttered: the inflection of the voice, the pitch, loudness, pace, stress, and the like. In speaking, both language (verbal aspects or words) and paralanguage (vocal aspects or sounds) play significant roles in conveying our meaning.
