Original Abstract Submitted

a method and an apparatus for detecting a relative location between devices is disclosed. the detection method includes: obtaining a first target audio signal obtained by a first microphone of a device b; determining a first audio segment and a second audio segment based on a first target moment and the first target audio signal, where the first target moment is a moment determined in the first target audio signal based on a target amplitude; separately searching for the first audio segment and the second audio segment to obtain a first arrival moment and a second arrival moment; and determining a relative location between a device a and the device b based on the first arrival moment and the second arrival moment.
