Articulatory gestures are the actions necessary to enunciate language. Examples of articulatory gestures are the hand movements necessary to enunciate sign language and the mouth movements of speech. In semiotic terms, these are the physical embodiment (signifiers) of speech signs, which are gestural by nature (see below). Articulatory gestures, when seen as the physical embodiment of speech and sign language symbols, provide a link between these two language types, and show how speech resembles sign language more closely than is generally presumed.
