Abstract: Highlights•The proposed method determines parts of a sentence that can be executed by gestures with utterance. This part is herein called an expression unit.•Gesture types are then predicted to characterize the expression unit in the sense of conveying thoughts and feelings.•Appropriate gestures are determined for each expression unit considering gesture types.•Experiments are analyzed for accuracy comparison on determining expression units and gesture types. In addition, comparisons of effectiveness are also verified in terms of human–robot interaction.
