To efficiently support realization of smooth and comfortable dialogues between an operator and a customer according to the customer's emotions.SOLUTION: In a voice characteristic change system, a receiver which receives and outputs a video and a spoken voice of an operator from an operator terminal, and a server are connected so as to be able to communicate. The receiver is connected to a camera which captures the customer viewing the video and spoken voice, and acquires the captured image of the customer captured by the camera, and sends it to the server. The server derives emotional data indicating emotions for the customer's video and spoken voice based on the captured image of the customer sent from the receiver, and generates and sends processing instructions for changes of the characteristics of the operator's spoken voice, based on the result of deriving the customer's emotional data. The receiver changes and outputs the characteristics of the operator's spoken voice based on the processing instruction sent from the server.SELECTED DRAWING: Figure 2 【課題】顧客の感情に合わせたオペレータと顧客との間のスムーズかつ快適な対話の実現を効率的に支援する。【解決手段】音声特性変更システムは、映像およびオペレータの発話音声をオペレータ端末から受信して出力する受信機と、サーバとが通信可能に接続される。受信機は、映像および発話音声を視聴する顧客を撮像するカメラと接続され、カメラにより撮像された顧客の撮像画像を取得してサーバに送る。サーバは、受信機から送られた顧客の撮像画像に基づいて、顧客の映像および発話音声に対する感情を示す感情データを導出し、顧客の感情データの導出結果に基づいて、オペレータの発話音声の特性の変更に関する処理指示を生成して受信機に送る。受信機は、サーバから送られた処理指示に基づいて、オペレータの発話音声の特性を変更して出力する。【選択図】図２
