This study aimed to quantify articulation rate among Hebrew speaking children and adolescents across a wide age range, and to assess whether age-related differences vary according to metric. One hundred and forty children, in seven age groups, participated in this cross-sectional study. All children were recorded during conversation and a picture description task, and articulation rate was measured using three metrics: word per minute (WPM), syllable per second (SPS) and phone per second (PPS). A significant increase in articulation rate was observed with age. Rate measurements during conversation were significantly faster than in picture description, and no gender differences were found. In general, the SPS and PPS metrics yielded equivalent results, which were different from those obtained with the WPM metric. Articulation rate among normally fluent children and adolescents increased with age. Furthermore, an increase in rate was evident after the age of 13 years.
