The effect of phonetic complexity on the speed of single-word productions in adults who do and do not stutter.

Purpose: The purpose of this study was to investigate the influence of phonetic complexity as measured by the Word Complexity Measure (WCM) on the speed of single-word production in adults who do (AWS, n=15) and do not stutter (AWNS, n=15).

Method: Participants were required to name pictures of high versus low phonetic complexity and balanced for lexical properties. Speech reaction time was recorded from initial presentation of the picture to verbal response of participant for each word type.
