Abstract

The invention provides a sweeping robot, the sweeping robot comprises a microphone array and a signal processing module connected with the microphone array, the microphone array comprises a first microphone and a second microphone, and the first microphone and the second microphone are used for collecting sound signals containing voice control signals emitted by a target sound source; the signal processing module is used for determining cross-correlation information corresponding to a first sound signal collected by the first microphone and a second sound signal collected by the second microphone; determining time difference information when a voice control signal emitted by the target sound source arrives at the first microphone and the second microphone based on the cross-correlation information; and performing delay compensation operation on the first sound signal and / or the second sound signal based on the time difference information to obtain pickup signals corresponding to the first microphone and the second microphone. According to the invention, the recognition accuracy of the voice recognition function and / or the control accuracy of the voice control function of the sweeping robot can be effectively improved, so that the user experience is effectively improved.

Description

technical field [0001] This application relates to the technical field of electrical appliances, in particular to a sweeping robot. Background technique [0002] In recent years, with the rapid development of intelligent technology, sweeping robots with voice control functions have emerged as the times require. However, the working noise generated by the sweeping robot during operation is extremely obvious. Whether it is environmental noise or working noise, it is very likely to affect the realization of the voice control function of the sweeping robot, thereby reducing the user experience. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present application is proposed. An embodiment of the present application provides a sweeping robot. [0004] An embodiment of the present application provides a sweeping robot, which includes a microphone array and a signal processing module connected to the microphone array, wherein the...
