Abstract: The present invention relates to an active sound device utilizing audio recognition, the device comprising a data input unit for inputting audio data from an external terminal, an output unit for outputting the inputted audio data, an audio detection unit for detecting an audio signal generated from outside, a determination unit for determining the audio signal detected by the audio detection unit, and a control unit for, on the basis of information determined by the determination unit, controlling the output of the audio data inputted from the data input unit.

Abstract: A data processing method according to the present invention comprises the steps of: receiving an input of video contents including a video stream and an audio stream; detecting music data from the audio stream; and filtering the audio stream so that the music data detected from the audio stream is removed.

Abstract: Provided are a device, method, and computer program for providing an acoustic recognition result with improved reliability. The method includes acquiring acoustic data, generating a plurality of pieces of acoustic sub-data by dividing the acoustic data, and generating acoustic recognition result information corresponding to each piece of acoustic sub-data by inputting the plurality of pieces of acoustic sub-data to an acoustic recognition model.

Abstract: In an embodiment of the present invention for solving the above-described problem, a method of improving recognition accuracy of acoustic data is disclosed. The method may include configuring one or more acoustic frames based on acoustic data, processing each of the one or more acoustic frames as an input of an acoustic recognition model to output predicted values corresponding to each acoustic frame, identifying one or more recognized acoustic frames through threshold analysis based on the predicted values corresponding to each acoustic frame, identifying a converted acoustic frame through time series analysis based on the one or more recognized acoustic frames, and converting a predicted value corresponding to the converted acoustic frame.

Abstract: Disclosed is a method for providing matching information through the analysis of sound information according to an embodiment of the present invention. The method may include a step for acquiring the sound information, a step for acquiring user feature information on the basis of the sound information, and a step for providing the matching information corresponding to the user feature information.
