Is Tongue Strength an Important Influence on Rate of Articulation in Diadochokinetic and Reading Tasks?

Abstract

Maximum tongue pressure, the pressure used to produce /t/, the proportion of maximum pressure used to produce /t/, and tongue endurance were poor predictors of diadochokinetic rates and articulation rate in reading for healthy speakers. Discussion Focus must remain on factors beyond strength, such as movement precision and coordination, to improve researchers' understanding of normal and disordered speech production in adults.
