Disﬂuent whole-word repetitions across the lifespan
Durational patterns and functions
Frequency of disﬂuencies in speech is often analysed in diﬀerent age groups, but functions of certain types of disﬂuencies are rarely examined. The aim of this study is to analyse durational patterns and functions of the repeated words in diverse age groups (from preschool children to elderly speakers). Functions of repetitions are well determinable from their durational patterns and pauses around the ﬁrst and second instances of the repeated words. Results show that disﬂuent word-repetitions are good predictors for detecting some age-dependent changes in speech production process.
