대화형 에이전트의 사용 범위와 기능이 점차 확장되고 있다. 특히나, 사용자의 호출이 있어야만 말을 하는 대화형 에이전트에서 사용자의 호출 없이도 먼저 말을 걸 수 있는 선제 발화하는 대화형 에이전트에 대한 연구와 기술개발이 이루어지고 있다. 그러나 아직 초기 단계이기 때문에 선제 발화하는 대화형 에이전트가 사용자에게 어떠한 영향을 미칠지에 대한 연구가 부족한 상황이다. 이에 이 연구는 선제 발화하는 대화형 에이전트가 사용자 경험에 미치는 영향을 확인하기 위해 사용자의 과제 수행 조건과 에이전트의 자기노출 유무를 독립변인으로 하는 2×3 혼합 설계를 통해 친밀감, 기능적 만족감, 심리적 저항감, 작업 부하를 측정하였다.

This paper aims to probe into the meaning of Ranhou in Mandarin Chinese and to account for discourse functions of it in radio call-in programme. For this purpose, the present study investigates the meaning of Ran and Hou repectively at first and explains the change of meaning of Ranhou, because we assume that Ranhou is compounded by Ran and Hou, and the core meaning is derived from its compounded meaning. Then we examine which time category Ranhou belongs to more based on the concept of time(reference, event, discourse) in Schiffrin(1987), and examine also where it is located within turn. Following this examination, we analysis and explain discourse functions what it is situated. Therethrough, we understand that 1) Ran has 'agreement or confirmation of preceded utterance' therefore has anaphoric meaning, and Hou has 'after' in the meaning cline: back of body-back part-behind-after-retarded(proposed by Heine et al. 1991), so that Ranhou has 'after agreement or confirmation of preceded utterance of mine' and extends to 'on premise preceded utterance or event' furthermore, and therefore can have possibility having various functions; 2) Ranhou has various functions in natural language in spite of the institutional setting. It can indicate (1) temporal relation of events, (2) logic relation of two(or more) events, e.g. causality, elaboration, concession, list, (3) turn maintence, acquisition, management, (4) verbal filler.

This study reports anti-hierarchical initial-syllable lengthening of an utterance-internal phrase in Korean. That is, the phrase-initial syllable (e.g., /a/ of "apa-do" or /ma/ of "mapa-do") starting with a voiced phoneme (i.e., vowels or voiced consonants) manifests itself as significantly longer when it is preceded by another phrase without a pause than when it leads an utterance or follows a pause utterance-internally. The phenomenon was examined with regard to two other factors: (1) tempo and (2) tenseness of the consonant (/p, $p^{\prime}$, $p^h$/) following the target syllable /a/. First, the effect of tempo on initial lengthening was not significant. Apart from the statistical significance, however, a tendency was observed, i.e., the slower the tempo is, the greater the lengthening. By contrast, the faster the tempo is, the higher the ratio (%) of lengthening. Second, contrary to our expectations, initial-syllable lengthening was even greater before tense stops /$p^{\prime}$, $p^h$/ than before lax stop /p/ regardless of tempo, and it was remarkable when it comes to the ratio (%), which means that initial lengthening is free of the pre-consonantal vowel shortening effect. Final-syllable lengthening is a pre-boundary marker, while the initial-syllable lengthening is regarded as a post-boundary marker of a phrase.
