Effects of speaking task and proficiency on the midclause pausing characteristics of L1 and L2 speech from the same speakers

Abstract

AbstractThis study explored the effect of speaking task on midclause pausing characteristics in the L1 and L2 speech of the same speakers to gain further insights into the potential relationship between pause location and stages of speech production. Participants included English L1 learners of L2 French (n = 29) or Spanish (n = 27) from the publicly available, longitudinal LANGSNAP corpus. Participants completed two oral tasks in their L1 and L2: a picture-based narrative and a semistructured interview. The rate, duration, and proportion of midclause pauses were compared between tasks in the L1 as well as in the L2 before and during residence abroad. In the L1, results indicated more fluent performance in the narrative task except for rate. When speaking in their L2, participants showed improvement on each measure in the narrative task but ultimately remained less fluent in their L2 in comparison to their L1. In the interview task, the only measure of midclause pausing that consistently differentiated L1 from L2 speech was midclause pause rate. The findings call for a nuanced interpretation of connections between midclause pausing and formulation and suggest that midclause pause rate is least influenced by speaking task.
