“…Individual differences affecting L1 speech fluency are likely to be reflected in L2 fluency measures as well (e.g., De Jong et al, 2015;Huensch & Tracy-Ventura, 2017). For instance, although not explicitly studying within-group variation, some L2 fluency studies have demonstrated relatively large standard deviations especially in the use of filled pauses and repetitions both in native and L2 speech (e.g., Brand & Götz, 2011;Cucchiarini, Strik, & Boves, 2002;Götz, 2013;Kahng, 2014;Peltonen & Lintunen, 2016), which suggests that at least these aspects of fluency are subject to individual variation (see also Fehringer & Fry, 2007). It has also been postulated that pause length is more related to individual speaking style than to L2 proficiency (e.g., Cucchiarini et al, 2002, Kolly et al, 2015but cf.…”
