Gestural Phonology (definition)
Gestural phonology is phonological model in which each sound is broken down into the individual articulatory actions that are used to produce a sound. For example, the first gesture in the word “Matt” is to pull one’s lips together to create the initial [m]. Under this model, sounds are described and stored as mental representations in terms of their composite gestures.
