Prosodic and Segmental Aspects of Pronunciation Training and Their Effects on L2

Abstract

Some studies on training effects of pronunciation instruction have claimed that the training of prosodic features has effects at the segmental level and that the training of segmental features has effects at the prosodic level, with greater effects reported when prosody is the main focus of training. This paper revisits this claim by looking at the effects of pronunciation training on Italian learners of German. In a pre-post-test design, we investigate acoustic changes after training in learners’ productions of two features regarded as prosodic and two features regarded as segmental. The prosodic features were the pitch excursion of final rises in yes–no questions and the reduction in schwa epenthesis in word-final closed syllables. The segmental features were final devoicing and voice onset time (VOT) in plosives. We discuss the results for three groups (with segmental training, with prosody training, and with no pronunciation training). Our results indicate that there are positive effects of prosody-oriented training on the production of segments, especially when training focuses on syllable structure and prosodic prominence (stress and accent). They also indicate that teaching segmental and prosodic aspects of pronunciation together is beneficial.
