Although previous studies employed transfer learning or reinforcement learning to characterize chat-oriented dialogue systems, these methods are only applicable to fine-tunable response generation models. Since response generation models in the proposed method can employ models of any size that cannot be fine-tuned or black-box models, we can benefit from the recent large language models. Our style transfer model is built by training the target character's utterance to remove the characterization via roundtrip translation and then reconstruct it.
