Device with convolutional neural network for acquiring multiple intent words, and method thereof

Abstract

The present disclosure relates to a convolutional-neural-network structure for acquiring intent words, and a speech recognition device and method using the network. the method includes receiving input data generated from speech, performing convolution on the input data and N3 filters each having N2 channels, and acquiring a feature map having N4 pieces of data for each channel, applying max pooling to the N4 pieces of data to acquire a representative value, and acquiring a feature map having N2 pieces of data for each filter, performing concatenation on the feature maps for the respective filters, and acquiring one feature map of an N3×N2 matrix, performing convolution on the feature map of the N3×N2 matrix and a filter of a 1×N3 matrix, and acquiring a feature map of a 1×N2 matrix; and inputting the feature map of the 1×N2 matrix into an artificial neural network, and acquiring at least one intent word.
