This paper, using the speech thinking of protocol analysis, tried to improve the reliability by quantified using a multivariate analysis to process that categorizes the results obtained from interviews conducted interviews. Japanese, “happy”, “fear, sadness, ” “surprise, anger” are plotted in a short distance. “Fear, sadness” is not distinguish, for example, between large and small and the voice of the low of the voice as a clue, “surprise, anger, ” it was found to be distinguished, such as How to put out of breath and the strength of the voice as a clue. Koreans, “fear-sad” is have been plotted in a short distance, “happy, anger, surprise, ” are plotted at a short distance. For Korean, it said to have been largely based on the overall voice intensity determination. Chinese “happy”, “fear”, “sad”, “anger, surprise” has been plotted at a short distance. Chinese plotted is different from speech feature position is different plot position by country of Japanese and Korean than experiment collaborators.
