This sound playing method relates to information processing field. After receiving a sound trigger command, the sound playing device determines the sound collection event corresponding to the sound trigger command. If all audio files included in the sound collection event are loaded in the memory of the sound playing device, the sound playing device directly plays the audio file corresponding to the sound collection event. The sound playing device does not load the audio file to the memory repeatedly, so as to reuse the audio files loaded in the memory, which reduces the memory usage and improves running efficiency of the applications or art animation effects.
