Methods and devices for flexible and adaptable outputting of audio files in text or audio format based on certain parameters are described. Before delivering an acquired audio file to a user, the methods and devices described herein detect a current value of a pre-specified parameter, such as an environmental noise parameter, a mute setting parameter, a ring tone setting parameter, an audio/video playback parameter, or a setting parameter of an application acquiring the audio file, and compare the current value of the pre-specified parameter with a preset condition for the same parameter. The methods and devices described herein with output the audio file or a text file created from the audio file depending on the result of the comparison.
