Abstract | The purpose of this study was to investigate the effect of female age on acoustic measures of voice production. Specifically; (1) Does female age affect cepstral peak prominence (CPP) in vowels and sentences? (2) Does female age affect fundamental frequency (Fo) in vowels and sentences? Participants were 34 females recruited into two different age groups: child (between 6-10 years; mean= 8.47 years) and young adult (between 19 - 25 years; mean=20.35 years). The KayPentax (Montvale, NJ) Computerized Speech Lab (CSL) and the software program PRAAT were used to record and analyze recordings of the vowels /i/ and /a/, as well as the fifth sentence from theConsensus Auditory Perception Evaluation of Voice. (CAPE-V) ANOVA analysis revealed that children displayed higher CPP values during production of the two vowels compared to adults, although the absolute difference was only 1.42dB and 1.46dB for the /a/ and /i/ vowels, respectively. Alternatively, the children exhibited lower values during connected speech compared to the adult females, though the difference was very small (0.25dB).For measures of Fo, female children always manifested higher values than the adults regardless of the stimulus. These findings support the hypothesis that acoustic output is influenced by the maturing speech mechanisms. |
