"While avatars are effective when teleoperated, they must also be capable of autonomous behavior in the absence of an operator. "In particular, avatars whose appearance closely resembles that of a real individual need to possess conversational abilities that reflect the personality of the person being modeled. This paper presents the development of a speech generation system that produces personality-consistent utterances using a large language model (LLM) and speech synthesis technology. Through system evaluation, we examined the factors contributing to the perception of individuality. Experimental results indicated that the utterances generated by the developed system were perceived as more characteristic of the modeled individual than those of the actual person. Furthermore, we found that the perceived identity of the utterances could influence the perceived identity of the voice itself.
