Provided is a man-machine interaction method and device based on an intelligent robot. The method comprises the steps of obtaining interaction voice information input by a user; uploading the interaction voice information to a cloud server, recognizing the interaction voice information through the cloud server, and receiving a cloud voice recognition result sent by the cloud server; after the voice information is uploaded to the cloud server and before the cloud voice recognition result sent by the cloud server is received, if new voice information input by the user is received, calling an off-line voice recognition module to recognize the new voice information input by the user to obtain an off-line voice recognition result, and generating corresponding multimode feedback information according to the off-line voice recognition result and outputting the multimode feedback information. According to the man-machine interaction method and device based on the intelligent robot, the problem that the new voice information input by the user cannot be responded to when the voice recognition result sent of the cloud server is waited for is solved, and thus the robot can feed back the voice interaction information input by the user more reasonably.
