Embodiments of the present invention disclose an audio processing method applied to a cloud interaction system. The cloud interaction system comprises user equipment and a server. The method comprises: a server monitors for calling of an audio interface via an interactive application, and, upon detecting that the audio interface has been called by the interactive application, the server generates, according to the type of audio interface, an audio instruction corresponding to the type, and determines whether there is a sending record indicating that audio data corresponding to the audio instruction has been sent to the user equipment; if there is a sending record, the server sending the audio instruction to the user equipment, wherein the audio instruction instructs the user equipment to use buffered audio data when executing the audio instruction. The audio processing method provided by the embodiments of the present invention can improve audio quality of user equipment, and reduce network traffic between servers and user equipment.
