We report basic findings on articulation rate effects derived from experimental research on children's sentence planning. The experiments were designed to evaluate production processes with attention to syntactic variables while controlling for lexical and phonological variables. Articulatory rate measures showed (1) rates differed for children (3–8.11) and adults, with adult rates significantly faster than child rates; (2) the effects of fluent and dysfluent host utterances on fluent substrings differed for adults and children; (3) rate patterns for relative clause and conjoined clause utterances differed, both from each other and across age group.
