Tongue movement of healthy young adults who feel clumsy articulating alveolar sounds in daily conversation was measured using the WAVE speech research system. Tongue blade movements of these speakers during repetitive production of Japanese /ra/ showed reduction of speed and movement range compared with those who feel no clumsiness, despite the absence of any organic or neurological abnormalities. Such differences may suggest underlying differences of fine and rapid motor controls required for smooth speech production which may be related to their awareness of clumsiness in articulation.
