Abstract	This study examined whether mean vocal fundamental frequency ("F"[subscript 0]) or speech sound pressure level (SPL) varies with changes in syllable repetition rate. Twenty-four young adults (12 M and 12 F) repeated the syllables/p[inverted v]/,/p[inverted v]t[schwa]/, and/p[inverted v]t[schwa]k[schwa]/at a modeled "slow" rate of approximately one syllable per second, at a self-selected "comfortable" rate, and at their maximum rate. For both male and female subjects there was a significant increase in "F"[subscript 0], but not SPL, between the "slow" and "maximal" and between the "comfortable" and "maximal" repetition rates. Conversely, there was no significant difference in mean "F"[subscript 0] associated with syllable type, whereas significant SPL differences were most likely due to differences in plosive aspiration, syllable stress, and juncture between the mono-, bi-, and tri-syllabic sequences. These results suggest that there is a laryngeal adjustment that attends an increase in speech rate, lending additional support for speech and voice treatment strategies that employ rate modification techniques. Learning outcomes: The reader will be able to: (1) outline the advantages and disadvantages of using a syllable-repetition task to evaluate speech rate; (2) describe how vocal "F"[subscript 0] and speech SPL are affected by changes in speech rate; and (3) describe the clinical and theoretical implications of the results from this study.
