The damage caused by communications fraud has become a major social problem, and various organizations and institutions are taking various countermeasures. However, it is difficult to deal with all of them because the keywords used in fraudulent calls change with the diversification of the methods. In this paper, we attempted to extract the speech characteristics of a suspect from the voice of a communications fraud. In this paper, we tried to extract the characteristics of the suspect's speech from the communications fraud voice. The results of morphological analysis showed that many words related to time were used, which gave a sense of urgency to the victims. In addition, the speaking speed was slightly faster than that of normal conversation. Using these results, we constructed a discriminant model for communications frauds and verified the classification accuracy.
