Abstract: A socio-emotive-cognitive architecture for a social robot that includes at least two of an attention system that determines at least one of the subject on which and the direction to which the robot focuses at least one of its resources in real-time; an embodied speech system that facilitates intent-based variation of utterances combined with multi-segment body movement; a motivation system that adjusts at least one of the degree of interaction and a mode of interaction for engaging a human user; and an emotion system that partially determines how the attention system, the embodied speech system, and the motivation system perform for any given interaction with a human.

Abstract: A social robot provides more believable, spontaneous, and understandable expressive communication via embodied communication capabilities by which a robot can express one or more of: paralinguistic audio expressions, sound effects or audio/vocal filters, expressive synthetic speech or pre-recorded speech, body movements and expressive gestures, body postures, lighting effects, aromas, and on-screen content, such as graphics, animations, photos, videos. These are coordinated with produced speech to enhance the expressiveness of the communication and non-verbal communication apart from speech communication.
