Speaking Fundamental Frequency

Speech samples from groups of White, African American, and Hispanic kindergarten-age children were compared on measures of mean speaking fundamental frequency (F o ), maximum and minimum speaking F o , pitch sigma, and speaking range (in semitones). Results indicate that there are significant differences between racial groups on measures of mean speaking F o and speaking range. In particular, the Hispanic children were observed to have increased mean speaking F O S in comparison with the African American children and reduced speaking ranges as compared to both African American and White racial groups. Results indicate that the speech-language pathologist must exercise discretion when assessing the speaking F o characteristics (particularly mean speaking F o and speaking range) of children from different racial groups.

Speaking Fundamental Frequency

The fundamental vocal frequency characteristics were measured from 50 male and 50 female Black 6-year-old children during prompted spontaneous speech. Boys had a mean fundamental frequency of 219.50 Hz, with a mean range of 134.80–298.70 Hz. Girls had a mean fundamental frequency (F 0 ) of 211.30 Hz and a mean frequency range of 137.60–297.50 Hz. No significant differences in mean or range values were found as a function of speaker sex. Nonsignificant relationships were found between physical variables of speaker height and weight and these F 0 measures for either sex and for the speaker group combined. The results of the present study were compared to previous research concerning the speaking fundamental vocal frequency of White children.
