The present study investigates the influence of utterance speed and pitch, two paralinguistic characteristics, on inference of personality, based on a two-stage inference hypothesis. The hypothesis assumes that traits from speech are inferred from paralanguage mediated by impression of speech. Participants were 49 native Japanese speakers who had normal hearing. Experimental stimuli were 9 speech tokens that had different speaking rates and pitches, which were created from an artificial voice. The experiment proceeded by having participants respond to 1 item after listening to each stimulus once. Items that asked participants about speech state impression and those that asked about personality were presented in different sections. Results of path analysis led to two models. The speech state impression formation model showed influence of paralanguage on impression formation of speech state. The trait inference model showed influence of paralanguage and formation of speech state impression on inference of personality. Thus, these results suggest that personality is inferred both directly from paralanguage, and indirectly from formation of speech state impression.
