Abstract
A study of linguistic variations in the speech accommodations of Korean teachers was carried out in order to test their ability to adjust utterances during lectures (using two phases: introduction and presentation of a grammatical rule), counseling sessions, and interview situations. A total of ten groups were recruited for six months. A number of acoustic cues, such as F0 distribution, length of utterances, number of syllables, speaking rate, articulation rate, duration of pauses, and syllable duration in prosodic units, were acoustically analyzed. The results of this study indicate the following. (1) Teachers accommodated their speech more during interactive activities with students (lecture and counselling), as compared to during an interview with a native Korean speaker, in terms of F0, number of syllables, and articulation rate. (2) In the presentation of a grammatical rule phase, teachers used a higher-pitched voice and longer pauses than in the introduction phase for the same lesson. (3) Teachers’ conversations during the counselling sessions had shorter pauses than during lectures, although their articulation rates were similar. This study confirms that Korean language teachers adjust their speech by changing its acoustic attributes. The significance of this study is its understanding of the prosodic characteristics of teachers' speech accommodation in prosodic units
