Claim 7:
8. The method according to claim 1, wherein a blank label is added to the labeling data, and the fusing the inter-class confusion measurement index and the intra-class distance penalty value comprises:
obtaining center vectors corresponding to categories to which the given label in the labeling data and the added blank label belong; and
calculating, for a depth feature sequence formed by the audio data stream for the depth feature in a time sequence, a probability that the audio data stream is mapped to a given sequence label and distances of the given sequence label respectively relative to the center vectors, to obtain an intra-class distance penalty value of the audio data stream relative to the given sequence label, the given sequence label comprising the added blank label and the given label.
