Figure 3.1. Steps in the transmission of a linguistic signal from one person to another.Spoken and signed languagesThe modality of spoken languages, such as English and Cantonese, is vocal, because they are articulated with the vocal tract; acoustic, because they are transmitted by sound waves; and auditory, because they are received and processed by the auditory system. This modality is often shortened to vocal-auditory, leaving the acoustic nature of the signal implied, since that is the ordinary input to the auditory system.
