Abstract: An electronic device includes memory; a communication module comprising an antenna array configured to form a plurality of candidate beams; and a processor connected to the communication module and the memory, the processor comprising a channel state classifier based on a neural network, wherein the processor is configured to: generate channel characteristic data based on information measured from the plurality of candidate beams for a signal received from a base station, input the channel characteristic data to the channel state classifier to infer a channel state between the electronic device and the base station, and reform the plurality of candidate beams based on the inferred channel state.

Abstract: Disclosed are method and apparatus for speech analysis. The speech analysis apparatus and a server are capable of communicating with each other in a 5G communication environment by executing mounted artificial intelligence (AI) algorithms and/or machine learning algorithms. The speech analysis method and apparatus may collect and analyze speech data to build a database of structured speech data.

Abstract: Disclosed is a sound analysis method and apparatus which execute an installed artificial intelligence (AI) algorithm and/or a machine learning algorithm and are capable of communicating with other electronic devices and servers in a 5G communication environment. The sound analysis method and apparatus provide a sound learning model specialized for a sound environment of a target space.

Abstract: An artificial intelligence apparatus for recognizing speech of a user includes a microphone and a processor configured to acquire, via the microphone, first speech data including speech of a user, generate a first speech recognition result corresponding to the first speech data, perform control corresponding to the generated first speech recognition result, generate an alternative speech recognition result corresponding to the first speech data if negative feedback is acquired from the user, and perform control corresponding to the generated alternative speech recognition result.
