Sa. Xue et al., Speaking F-0 characteristics of elderly Euro-American and African-Americanspeakers: building a clinical comparative platform, CLIN LING P, 15(3), 2001, pp. 245-252
This study sought to describe speaking fundamental frequency characteristic
s of elderly Euro-American and African-American individuals and to explore
the effects of ethnicity and ageing on vocal parameters of speech productio
n. Speech samples from 42 elderly Euro-American and 37 elderly African-Amer
ican individuals (age range: 70-80 years) were compared on measures of mean
speaking fundamental frequency (F-0), maximum and minimum speaking F-0, sp
eaking F-0 standard deviation (F-0 SD), and speaking F-0 range (in semitone
s). Elderly African-American females had significantly lower mean speaking
F-0 and speaking F-0 SD than their Euro-American cohorts. Results indicate
that researchers need to improve the clinical database for speakers from no
n-Euro-American backgrounds, and speech-language pathologists must exercise
discretion when assessing the speaking F-0 and other speech characteristic
s of elderly individuals from different ethnic groups.
