Vocal Frequency Measures in Normal Speaking Children and Children with Vocal Deviations. Final Report.
Leeper, Herbert A., Jr.; Iverson, Rachel L.
The report examines vocal frequency differences between normal speaking children and 65 children (mean age 9-years) with vocal nodules and accompanying vocal quality disturbances. In part I of the study children were screened by a physician and their voices were recorded and analyzed by a digitizer-computer system for mean vocal frequency, frequency variability, basal frequency, frequency range, and amount of frequency skewness for sustained vowel phonations. Among findings was that of the vocal frequency measures studied, only basal frequency differentiated the two groups. The second part of the experiment related 15 perceptual factors and one physical variable to the ratings of overall vocal efficiency. The results suggest that listeners can accurately scale voices along a severity continuum and relate this to judged voice characteristics. (Author/PHR)
