Document Type and Number:
WIPO Patent Application WO/2024/090858
Kind Code:
A1
Abstract:
A neuromorphic device for implementing a neural network may comprise: a memory in which at least one program is stored; an on-chip memory including a crossbar array circuit; and at least one processor which operates the neural network by executing the at least one program, wherein the at least one processor receives an audio signal and inputs the audio signal to the neural network trained on the basis of predetermined training data, to output a speech recognition result, and the neural network comprises: a Fourier transform layer that generates a frequency signal by converting the audio signal in a time band to be in a frequency band; a Mel generation layer that generates a Mel spectrogram from the frequency signal; and an output layer that outputs the speech recognition result on the basis of a speech feature of the Mel spectrogram.
