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 n2D feature map as training data.

Electronic device for recognizing sound and method thereof

An electronic device including a microphone; an output interface; and a processor configured to: based on a word registered on the electronic device by a user, detect a voice of a talker who utters the registered word from an audio signal received through the microphone; based on voice information of a registered talker who is registered on the electronic device, determine whether the detected voice is a voice of the registered talker; and based on the detected voice being determined as the voice of the registered talker, control the output interface to output a voice notification, wherein the registered word refers to the user.

Electronic device and controlling method thereof

An electronic apparatus is provided. 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.

Electronic apparatus and controlling method thereof

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.
