Classification: CPC G | IPC G

Claim 17:
18. A non-transitory computer-readable storage medium storing computer program instructions executable by at least one processor to perform:
obtaining an audio data stream for neural network training of audio recognition, the audio data stream including audio data respectively corresponding to a plurality of time frames;
performing, for different audio data of each time frame in the audio data stream, feature extraction in each layer of a trained neural network, to obtain a depth feature outputted by a corresponding time frame;
fusing, for a given label in labeling data, an inter-class confusion measurement index and an intra-class distance penalty value relative to the given label in a set loss function for the audio data stream through the depth feature; and
obtaining, through fusion, a loss function value relative to a series of given labels in the labeling data, to update a parameter in the neural network.
