Claim 14:
15. The device according to claim 9, wherein the at least one instruction further causes the processor to:
acquire frame time-domain information by slicing acquired audio file data to be trained by using a moving window;
acquire magnitude spectrum feature training data and voiceprint feature training data by feature extraction on the frame time-domain information, wherein the feature extraction of the frame time-domain information comprises: magnitude spectrum feature extraction and voiceprint feature extraction;
acquire third fixed-length data by averaging the magnitude spectrum feature training data;
generate feature vector training data by splicing the magnitude spectrum feature training data and the voiceprint feature training data; and
acquire the voice classification model by training the third fixed-length data and the feature vector training data.
