Understanding one's character through the voice: Dimensions of personality perception from Chinese greeting word "Ni Hao".

Previous western studies revealed a two-dimensional model (valence and dominance) in voice impressions. To explore the cross-cultural validity of this model, the present study recruited Chinese participants to evaluate other people's personality from recordings of Chinese vocal greeting word "Ni Hao". Principal Component Analysis (PCA) with Varimax Rotation and Parallel Analysis was used to investigate the dimensions underlying personality judgments. The results also revealed a two-dimensional model: approachability and capability. The approachability dimension was similar to the valence dimension reported in a previous study. It indicated that the approachability/valence dimension has cross-cultural commonality. Unlike the dimension of dominance which was closely related to aggressiveness, the dimension of capability emphasized the social aspects of capability such as intellectuality, social skills, and tenacity. In addition, the acoustic parameters that were used to infer the personality of speakers, as well as the relationship between vocal attractiveness and the personality dimensions of voice, were also partially different from the findings in Western culture.
