The purposes of this study were to describe the characteristics of the changing male voice in 4th, 5th and 6th grade students using Cooksey's maturation stages and, to compare the age-of-onset of the male voice change in African American, White, and Hispanic male students. Participants included volunteer 4th (n = 61), 5th (n = 73), and 6th grade male students (n = 63) from 2 urban elementary schools, 5 suburban elementary schools, 1 suburban middle school and 1 urban middle school in the North Texas region. The three ethnic groups represented in this study were: African American (n = 62), White (n = 58), and Hispanic (n = 77). Results indicated that approximately 46% of 4th grade participants, 62% of 5th grade participants, and 67% of 6th grade participants were classified as changing voices. A descriptively larger percentage of African American participants were classified as changing voices than Hispanic and White participants. Also, a larger percentage of African American and Hispanic participants were descriptively classified in the more advanced stages of the voice change than White participants. Urban African American, White, and Hispanic participants had a larger percentage of males classified as changing voices than suburban African American, White, and Hispanic participants. Results of a one-way, between subjects ANOVA revealed no significant main effect for ethnicity, F (2, 51) = .42, p = .66, η2 = .02. The overall mean age-of-onset for participants in this study was approximately 11.20 years of age.
