Pedagogical and Acquisitional Implications of the Intonational Map Provided by Korean Textbook Example Conversations

Through the analyzation of a corpus of K-ToBI annotated speech taken from beginning level textbook conversation recordings, this paper aims to determine the global attributes of Slow, Clear Speech (SCS) on Korean prosody production, and to implicate these effects in the pedagogy of beginning-level Korean. In an analysis of the features that make Korean SCS distinct, four common themes emerged. First, there is final lengthening on Accentual Phrases (APs). Second, there are additional pauses and breaks between APs. Third, there is broad use of pitch reset and of focus in small syntactic frames. And fourth, boundary tones are typically flat and disaffected. Intonation plays a key role in the pursuit of L2 Korean intelligibility and is integral to strong acquisition of Korean. However, instructors rarely speak at normal speech rates (SR) with normal articulation, and typically use SCS with their beginning students. Students will recall frequently heard or salient intonational patterns, so instructors must take care to use intonational patterns intentionally. Thus, it is proposed that instructors of beginner students give explicit instruction and direct feedback on intonation and show natural speech examples often from various speakers, among other strategies to mitigate the effects of SCS on student intonational acquisition
