Audio decoding method, electronic device, and computer-readable storage medium based on label information vector

An electronic device, comprising:

• a memory, configured to store computer-executable instructions;
• and
• a processor, configured, when executing the computer-executable instructions stored in the memory, to implement:
• obtaining a bitstream of an audio signal;
• performing label extraction processing on a predicted value of a feature vector of the audio signal associated with the bitstream to obtain a label information vector, comprising:
• performing convolution processing on the predicted value of the feature vector to obtain a first tensor having a same dimension as the predicted value of the feature vector;
• performing feature extraction processing on the first tensor to obtain a second tensor having a same dimension as the first tensor;
• performing full-connection processing on the second tensor to obtain a third tensor having a same dimension as the second tensor;
• and
• activating the third tensor to obtain the label information vector, a dimension of the label information vector being the same as a dimension of the predicted value of the feature vector;
• performing signal reconstruction based on the predicted value of the feature vector and the label information vector;
• and
• identifying a predicted value of the audio signal obtained by the signal reconstruction as a decoding result of the bitstream.
