Outline of Final Research Achievements

(1) A multimodal corpus of gaming interaction that easily induces interlocutors' shouts was developed. This corpus contains more than ten times of shouts compared to existing corpora. Analysis of the shouts revealed the acoustical differences to regular words or interjections.
(2) A taxonomy of expressive interjections was developed, which enabled the synthesis of the interjections "a" with various forms. A perceptual experiment using the synthesized interjections revealed the relationship between the forms and paralinguistic information.
(3) Factors that affect the acoustical properties of laugh calls were identified. Incorporating these factors into the definition of context for the framework of the HMM-based speech synthesis enabled a flexible laughter synthesis. A perceptual experiment revealed the advantage of incorporating these contextual factors with respect to the naturalness of synthesized laughter.
