Abstract
Prosodic, or expressive, reading is considered to be one of the essential features of the achievement of reading fluency. The purpose of this study was to determine (a) the degree to which the prosody of syntactically complex sentences varied as a function of reading speed and accuracy and (b) the role that reading prosody might play in mediating individual differences in comprehension. Spectrographic analysis of 80 third graders' and 29 adults' reading of a syntactically complex text was carried out. Oral reading skill was measured through standardized assessments. Pitch changes (changes in fundamental frequency) and pause duration were measured for sentence-final words of basic declarative sentences, basic declarative quotatives, wh questions, and yes-no questions; words preceding commas in complex adjectival phrases; and words preceding phrase-final commas. Children who had quick and accurate oral reading had shorter and more adultlike pause structures, larger pitch declinations at the end of basic declarative sentences, and larger pitch rises at the end of yes-no questions. Furthermore, children who showed larger basic declarative sentence declinations and larger pitch rises following yes-no questions tended to demonstrate greater reading comprehension skills.
