Lifelog device utilizing audio recognition, and method therefor

A lifelog device comprising:

• an ear equipment configured to be worn by a user, the equipment including:
• an input unit to which lifelog data including an audio signal and biological information including at least one of a user's pulse rate or a user's body temperature is input through a sensor;
• a time setting unit configured to set a time for which the lifelog data is input to the input unit;
• an analysis unit configured to extract an analysis value from the input lifelog data;
• a determination unit configured to classify a class of the lifelog data on the basis of the extracted analysis value;
• a recording unit configured to record data including the input lifelog data and the classified class of the lifelog data;
• and
• a search unit configured to search for the recorded data,
• wherein the search unit extracts the recorded data which matches keyword information input by the search unit,
• wherein the search unit provides at least one of a number or a time of the recorded data corresponding to the classified class,
• wherein the lifelog data is input for a time preset by the time setting unit,
• wherein the analysis unit transmits the analysis value extracted from the audio signal and the biological information included in the input lifelog data to the determination unit,
• wherein the determination unit classifies the class of the lifelog data on the basis of a combination of the analysis value of the audio signal and an analysis value of the biological information using an artificial intelligence algorithm which is installed in advance,
• wherein the artificial intelligence algorithm is trained with a user's feedback on a determination value determined by the determination unit,
• wherein the determination unit matches the determination value for the lifelog data with information related to a place in which the lifelog data is input, and transmits the determination value and the information matching each other to the recording unit, and
• wherein the recording unit records the determination value for the lifelog data determined by the determination unit and removes data determined to be a noise class.
