APSIPA ASC 2009: Asia-Pacific Signal and Information Processing Association, 2009 Annual Summit and Conference. 4-7 October 2009. Sapporo, Japan. Oral session: Synthesis of Various Affective Speech Based on Knowledge of Human (6 October 2009).

In this study, we conducted a comparative experiment on emotion perception among different cultures. Emotional components were perceived by subjects from Japan, the United States and China, all of whom have no experience living abroad. An emotional speech database sans linguistic information was used in this study and evaluated using three- and/ or six-emotional dimensions. It was found that most speech materials were perceived to have multiple emotional components, even though the speakers intended to express a single emotion in the data collection. Based on the principle component analysis (PCA), the common factors could explain about 67% variance of the data among the three cultures by using a three-emotion description, and could explain about 53% variance between Japanese and Chinese cultures by using a six-emotion description. The emotions anger, joy and sad have the same structure in PCA based low dimensional spaces derived from the three-emotion and six-emotion descriptions, while the emotions Disgust, surprise, and fear appeared in the six-emotion derived low dimension space as paired counterparts of anger, joy and sad, respectively. The similarity of subspaces consisting of these two emotion groups was around 0.9. This indicates that the emotions anger, joy and sad can be considered as basic emotions.
