The purpose of this study was to augment dated normative studies of typical voice evaluation tasks. One hundred women aged 19-24 years completed several speech tasks. The following were calculated using the Speech Filing System software: s/z ratio, maximum phonation time (MPT), sustained pitch (fo), and diadokokinetic rates (DDK). Results indicated the one hundred female participants were comparable to previously published studies for DDK and Fo; however, they exhibited shorter phoneme durations.
