Articulation rate is a common
measure used in the evaluation of speech and fluency. The purpose of this study
was to examine differences in articulation rate in children and adolescents. One-hundred
and forty Hebrew-speaking children, age 3 to 17, were examined in two speaking
tasks: conversation and picture-description. Measurements were performed using
three metrics: word-per-minute (WPM), syllable-per-second (SPS) and
phone-per-second (PPS). In addition, diadochokinetic
(DDK) rate was evaluated. Results indicated that articulation- and DDK-rates
increased with age, but not linearly. Articulation rate was faster during
conversation than during picture-description, with no significant gender
differences. Rate measurements among the Hebrew speakers were typically higher
than those reported among English speakers.
