Abstract
The purpose of this study was to determine how proficiently children identify the gender of adults and children based upon perception of voiced and whispered vowels. On the average, children’s performance was similar to adults when judgments were based on adult speakers’ phonated and whispered vowels. This indicated that preadolescent listeners were sensitive to the differences in adult laryngeal and vocal tract size characteristics attributable to sexual dimorphism. Children and adults obtained similar average rates of accuracy when identifying gender based upon preadolescent children’s phonated vowels, but the children were not as reliable as adults. Adults were more accurate and more reliable than children when perceiving whispered vowels, the condition where spectrum envelope alone provided primary cues about children’s gender.
