Active listening is a crucial attitude with positive acceptance and empathy in counseling. This study proposed and designed the active listening agent, which notified the internal state, using Artificial Subtle Expression (ASE). It is a method to notify an internal state considering versatility and easy introducing to various agents, such as light blinking and beep sound. We incorporated the function of synchronous response to negative emotion into ASE. The agent judged its emotion from speech volume recorded in real time and output ASE's increasing beep sound, which corresponds to the speaker's voice quality. These were referred by the findings that empathy is encouraged when an agent's facial expression matches a participant's emotional state and that in negative emotion, speech volume is louder and the feature is easy to judge. We primarily explain the basic structure of the designed active listening robot and ASE's algorithm.
