Disclosed is an apparatus for determining goodness of fit related to microphone placement capable of communicating with other electronic devices and an external server in a 5G communication network, in which an artificial intelligence (AI) algorithm and/or a machine learning algorithm are executed. The apparatus includes an inputter, a communicator, a storage, and a processor. As the apparatus is provided, sound recognition effects can be improved.

Method and apparatus for determining goodness of fit related to microphone placement

Disclosed are a sound processing apparatus and a sound processing method. The sound processing method includes extracting a desired voice enhanced signal by a sound source separation and a sound extraction. By using a multi-channel blind source separation method based on independent vector analysis, the desired voice enhanced signal is extracted from a channel having the smallest sum of off-diagonal values of a separation adaptive filter when the power of the desired voice signal is larger than that of other voice signals. According to the present disclosure, a user may build a robust artificial intelligence (AI) speech recognition system by using sound source separation and voice extraction using eMBB, URLLC, and mMTC techniques of 5G mobile communication.

Method and apparatus for sound processing

Disclosed is an acoustic control method for operating an acoustic control system and apparatus by executing artificial intelligence (AI) algorithms and/or machine learning algorithms in a 5G environment connected for Internet of Things. An acoustic control method for adjusting a sound according to an embodiment of the present disclosure may include collecting one or more acoustic signals in a vehicle through at least one microphone provided in the vehicle, analyzing the acoustic signals in the vehicle, and adjusting volume and equalizer settings of an acoustic service being outputted through a speaker provided in the vehicle in response to the analyzed acoustic signals in the vehicle.

Acoustic control system, apparatus and method

Disclosed are a headset and an operating method thereof, which execute a mounted artificial intelligence (AI) algorithm and/or machine learning algorithm and communicate with different electronic apparatuses and external servers in a 5G communication environment. The headset includes a plurality of microphones, an AEC, a VAD, and a BSS, which process sound signals received from the microphones, resulting in improved convenience for a user.

Headset and operating method thereof

An aperture-shaped variable valve which is used for a semi-active control. The variable valve includes a ring-shaped aperture frame, a plurality of aperture plates which is arranged in a ring shape by overlapping each other on the aperture frame and forms an aperture, a restoring ring which fits into the outside of an aperture surface, and a spring which is connected between the restoring ring and the aperture frame.
