Volume control method and device of robot, storage medium and robot

The invention provides a volume control method and device of a robot, a storage medium and the robot, and relates to the technical field of sweeping robots. The volume control method comprises the steps of determining a starting point time point and an ending point time point of a first interactive voice under the condition that the first interactive voice is detected; acquiring a first audio corresponding to the first interaction voice according to the starting point time and the ending point time; determining a direct sound signal and an reverberant sound signal corresponding to the first audio; determining a first reverberation ratio according to the direct sound signal and the reverberation sound signal; and determining the voice response volume of the robot according to the first reverberation ratio. According to the technical scheme, the voice frequency of the user interaction voice in the current voice interaction event is accurately acquired, and the voice response volume of the robot is adjusted based on the reverberation ratio of the voice frequency, so that adaptive adjustment of the voice response volume of the robot can be realized, and the voice response volume of the robot can always accord with a current actual scene.
