In second language (L2) fluency research, (dis)fluencies are often examined from monologue speech without reference to the speakers' visual-gestural behavior or first language (L1) data. However, research on L1 and L2 gestures has revealed an intricate relationship between gestures and (dis)fluency, underscoring the need for more research on the topic. Extending these two lines of research, this pilot study examines the interplay between speech fluency and gesture in L1 Finnish and L2 English task-based interactions (N = 8). The data were collected as part of a larger project. The fluency-related features (fluencemes) examined in the present study included silent and filled pauses, prolongations, and four repair features. The functional gesture types included referential (deictic and representational) and pragmatic (discursive, interactive, and thinking) gestures. The gestures were also coded for the degree of overlap (full, partial, or no overlap) with fluencemes. Our results showed that the gestures and fluencemes were more frequently produced in the L2 than in the L1, but the distributions of gesture and fluenceme types were relatively similar across L1 and L2 interactions. The majority of gestures did not overlap with fluencemes, corroborating previous findings. The findings have implications for L2 speech fluency and gesture research.
