Purpose: This study investigated the effect of age on articulatory movement and stability in young, middle-aged, and older adults. It also examined the potential influence of linguistic complexity on speech motor control across utterances that differed in their length and grammatical complexity.
Method: There were 60 participants in three age groups: 20-30 years, 40-50 years, and 60-70 years, with equal numbers of men and women in each group. The speakers produced 10 repetitions of five different stimuli, each of which included the same bilabial-loaded phrase in different grammatical contexts, while their lip movements were recorded.
