| Research Abstract |
We constructed a natural conversational dialogue speech database, including linguistic, prosodic and paralinguistic information. A new acoustic parameter was proposed for breathy voice quality. Monosyllabic interjection utterances (such as "un", "oh", "haa") were extracted from the database, and the relations between speaking style and speech acts were analyzed. A set of interjections expressing different meanings were made available in the web. Automatic identification of speech acts were also evaluated, indicating the effectiveness of the proposed acoustic features. Repeated interjection utterances (such as "unun") were also analyzed, indicating relation between the number of repetitions and the paralinguistic functions. Question-type utterances were also analyzed, indicating relations between the phrase final intonation and the inter-personal relationship.
