This investigation compared vocal acoustic characteristics of African-American, Hispanic, and Caucasian women. Recordings were made during sustained phonation of the vowels /i/ and /a/. The samples were analyzed via the Voice Analysis Program of the Computerized Speech Laboratory, and measures for pitch, jitter, shimmer, and harmonics-to-noise ratio were obtained. Statistical comparisons showed no differences between the groups, suggesting that further exploration of normal acoustic characteristics across speakers of different ethnicities is warranted to determine if the same trends are found as the phonetic complexity of the samples increases.
