Abstract: An electronic apparatus is disclosed. The electronic apparatus may include a microphone; a memory configured to store a wakeup word; and a processor configured to: identify, based on context information of the electronic apparatus, an occurrence of a pre-determined event; change, based on the occurrence of the pre-determined event, a first threshold value for recognizing the wakeup word; obtain, based on a first user voice input received via the microphone, a similarity value between first text information corresponding to the first user voice input and the wakeup word; and perform, based on the similarity value being greater than or equal to the first threshold value, a voice recognition function on second text information corresponding to a second user voice input received via the microphone after the first user voice input.

Abstract: An example sound recognition method may include sampling input sound based on a preset sampling rate; performing Fast Fourier Transform (FFT) on the sampled input sound based on at least one of random FFT numbers or random hop lengths, and generating a two-dimensional (2D) feature map with a time axis and a frequency axis from the sampled input sound on which FFT is performed; training a neural network model, which recognizes sound, with a plurality of 2D feature maps including the first 2D feature map and an nth 2D feature map as training data.

Abstract: An electronic apparatus and a controlling method thereof are provided. The controlling method includes, based on an audio signal being received through a microphone, determining whether a user is on a public transport; detecting whether the audio signal includes a voice signal output through an acoustic device of the public transport; determining whether the voice signal from the acoustic device includes a voice signal for guiding at least one stop from among a plurality of stops; and outputting information on the at least one stop.

Abstract: An electronic apparatus is provided. The electronic apparatus may include a communication interface; and a processor configured to: control the communication interface to output an audio content signal to a sound input/output device including a speaker and a microphone; based on receiving a sound signal collected via the microphone from the sound input/output device via the communication interface, identify whether the sound signal includes a scene noise signal corresponding to a regular noise generated in a location in which the sound input/output device is located or an event noise signal corresponding to an irregular noise generated in the location in which the sound input/output device is located; based on identifying that the sound signal includes the scene noise signal, perform noise cancelling for the sound signal; and based on identifying that the sound signal includes the event noise signal, control the output of the audio content signal
