Data output apparatus and method, and computer-readable recording medium

A data output apparatus comprising:

• a first reception unit configured to receive unit-time or unit-size auditory data which are generated around a user and detected by a first apparatus;
• a filter unit configured to remove noises from the auditory data;
• a measurement unit configured to extract a frequency component included in the auditory data from which the noises have been removed and measure at least one frequency of the auditory data on the basis of the frequency component;
• a search unit configured to search a database on the basis of the at least one frequency to find reference data oscillating at the at least one frequency;
• an output data generation unit configured to generate first output data providing semantic data included in the reference data;
• and
• an output unit configured to generate and provide an output control signal for transmitting the first output data,
• wherein after the first output data is generated, the output unit generates second output data providing guide data linked to the reference data, and provides the output control signal after modifying the output control signal to additionally transmit the second output data.
