| Abstract(in English) | This paper presents our analyses of human-human and human-machine interactions and the characteristic differences of linguistic and acoustic features observed in different spoken dialogue situations and with different dialogue partners. The linguistic and acoustic features of the user's speech to a spoken dialogue system and a human operator are compared in several goal setting and destination database searching tasks for a car navigation system. It is said that it is not clear enough whether different dialogue situations, different dialogue partners and different speech recognition rate cause any differences of linguistic or acoustic features on one's utterances in a speech interface system. Additionally, research about influence of voice quality is not enough either. We prepared two patterns where we have two dialogue partners with different speech recognition rate (100% and about 80%). We also prepared three voice patterns (natural voice, synthetic voice and recorded voice). We analyzed the characteristic differences of user utterances caused by different dialogue situations and by different dialogue partners. Furthermore, we analyzed the differences based on user's impression of dialogue partner and a spoken dialogue system using questionnaires. As a result, we found that voice quality and rhythm of partner's utterance affect user's utterances, and an impression of dialogue partner is subject to voice quality. Additionally, we also found that a prejudice toward machines affects user's utterances. |
