Is L2 pronunciation affected by increased task complexity in pronunciation-unfocused speaking tasks? 

Grounded on the Cognition Hypothesis (Robinson, 2011), this studyexamines the effects of task complexity on L2 pronunciation accuracyand global pronunciation measures in pronunciation-unfocused tasks,and assesses the relationship between acoustic and listener-basedpronunciation measures. Eighty-two...
