Abstract

A study was conducted to determine if use of a lognHz scale would eliminate the effect of vocal tract size on vowel area across a broad age range of talkers and also be sensitive to potentially smaller vowel areas of dysarthric individuals. For this purpose, recordings produced by six 3 year-old children, six 5 year-old children and six young women, all with normal speech development, and six 5 year-old children with dysarthria were analyzed. It was found that vowel area, when measured in Hz2 and logn Hz2, decreases in size as age increases, suggesting that a lognHz scale does not normalize age differences in F2 and F1 vowel area.
