The invention discloses an output control method for a robot and a robot. The method comprises: first multi-modal data are outputted; during the outputting of the first multi-modal data, a user input is received; when the user input includes a request of outputting second multi-modal data, whether the first multi-modal data and the second multi-modal data can be outputted in parallel is determined; if not, the output of the first multi-modal data is interrupted and the output of the second multi-modal data is carried out. With the method, phenomena of an output conflict and data accumulation and blocking because of continuous receiving of output requests of a plurality of multi-modal data by a robot can be avoided; the output stability of the robot during the interaction process can be guaranteed effectively; the interactive output error is prevented; and thus the user experience is improved substantially.
