Abstract
Two studies were conducted to examine speaking rate following traumatic brain injury (TBI) in childhood and adolescence. Study 1 focused on longitudinal changes in speaking rate in 9 subjects with severe TBI and their age-matched control subjects. Physical measurements of speaking rate (in syllables/sec) were made from spontaneous speech samples obtained from each subject during three sampling sessions over a 13-month period. Although the average speaking rate of the group with TBI was slower than that of the control group at all three sampling sessions, an examination of the data from individual subject pairs revealed markedly slower speaking rates in only 5 of the 9 subjects with TBI at the final sampling session. The perceptual significance of slowed speaking rates in these 5 subjects was confirmed through subjective ratings by naive listeners. In Study 2, the contributions of two potential causes of slowed speaking rate were explored: reduced articulatory speed and increased pausing believed to be associated with linguistic processing difficulties. It is hypothesized that articulatory speed and linguistic processing speed may contribute independently to slowed speaking rates more than 1 year after TBI.
