Method for measuring distance by using intelligent voice module

The invention belongs to the technical field of smart home, and particularly relates to the technical field of sound pickup of smart home appliances, in particular to a method for measuring distance by using an intelligent voice module. The method comprises the following steps: setting four paths of MICs, grouping every two paths of MICs as a group, defining the groups as a first group of MICs anda second group of MICs respectively; setting the center distance between the first group of MICs and the second group of MICs to be C; measuring an included angle theta between the first group of MICs and a sound source and an included angle alpha between the second group of MICs and the sound source; setting the vertical distance between the sound source and the four MICs to be H, setting the horizontal distance between the central position of the first group of MICs and the sound source to be X1, and setting the horizontal distance between the central position of the second group of MICs and the sound source to be
