Abstract
-
The two purposes of the study were (1) to explore the nature of durational changes preceding and following a "clear" instance of stuttering event in the context of speech planning unit, namely, a clause, and (2) to explore (a) the trend of speech rate variables--total articulation time and total pause time--during the course of adaptation in stutterers and fluent speakers, and (b) elucidate the relation between the speech rate variables and fluency enhancement during adaptation. Four stutterers and their controls read a passage five times in succession. To explore the issues raised by the first purpose, five readings of each one of the eight candidate clauses with last word of the previous clause and first word of the succeeding clause were earmarked for spectrographic analysis. The first reading of each candidate clause contained a clearly identifiable stuttering event, with the other four readings being fluent. Word locations X - 2, X - 1, X + 1, X + 2 within the candidate clauses, and Xp and Xf outside them were defined in relation to stuttered word location (X). Within and between group comparisons of duration of words in these locations were carried out by using ANOVA by repeated measures. Significant durational changes in words occupying locations X - 1 and X in the immediate vicinity of stuttering events and Xp location (the last word of the previous clause) were noted. The result of this analysis has been discussed in the light of speech planning literature, hypotheses on moments of stuttering. To explore the issues raised by the second purpose, frequency counts of stuttering events in the five readings for the four stutterers were determined, speech rate variables, total articulation time and total pause time were defined and computed. Comparisons between stutterers and fluent speakers using ANOVA by repeated measures of speech rate variables for the five utterances of each one of the eight candidate clauses in the two groups of speakers were made. Similar comparisons were made on five totally fluent utterances of two candidate clauses by the eight speakers during the course of adaptation. The nature of relation between fluency enhancement during adaptation trials and rate variables such as total articulation time and total pause time is discussed.
