Dual-route models of speech production suggest that high-frequency forms are encoded in different ways from low-frequency and novel forms [7,15,16]. There is some evidence to suggest that lexical status may have some influence on stuttering behaviour, with higher incidences of stuttering being observed for low frequency words [4,9]. this paper reports on a study, which investigated the production of high and low frequency words, and non-words in two groups of young adult male speakers. The first, comprised a group of speakers with stuttering (N=4), and the second, speakers without stuttering (N=5). three repetitions were elicited from each subject via a repetition task and reocrded onto DAT. These data were subsequently digitsed at a sampling rate of 20 kHz. Two parameters were measured (in milliseconds) from the digitised samples using a KAY Elemtrics Computerised Speech Lab: 1) Response latencies (time taken to respond to a stimulus); and 2) word durations (duration of unterance). We report here on the first repetition of the high/low frequency and non-words.
