FIELD: information technology.
SUBSTANCE: in a system, wherein a transmitting device and a receiving device communicate with each other, the transmitting device has a first output module which outputs a first audio instruction and a transmitting module which transmits to the receiving device an output instruction, which instructs the receiving device to output a second audio instruction associated with the first audio instruction during a corresponding time for outputting a first guide, and the receiving device has a receiving module which receives an output instruction transmitted by the transmitting module, and an output module which outputs a second audio instruction in time according to the output instruction received by the receiving module.
EFFECT: broader functional capabilities by controlling time for playing back audio using corresponding devices such that there is no overlapping of audio when multiple devices playback audio.
