The voiceprint recognition method comprises: collecting, by a client, a test voice of a user, and sending a voice recognition request to the background server, the voice recognition request comprises the user ID and the test voice; receiving, by the background server, the voice recognition request, and determining the voice recognition request to be processed with a message queue and an asynchronous mechanism; acquiring, by the background server, a target voiceprint feature which corresponds to the user ID of the voice recognition request to be processed, and acquiring a test voiceprint feature which corresponds to the test voice of the voice recognition request to be processed; judging, by the background server according to the target voiceprint feature and the test voiceprint feature, whether the target voiceprint feature and the test voiceprint feature correspond to the same user, and outputting the result of the judging to the client; and receiving and displaying, by the client, the result of the judging. The voiceprint recognition method may achieve a fast voice recognition effect and improve the voice recognition efficiency.1/2 S10 collecting, by a client, a test voice of a user, and sending a voice recognition request to the background server, the voice recognition request comprises a user ID and the test voice receiving, by the background server, the voice recognition request, and determining the S20 voice recognition request to be processed with a message queue and an asynchronous mechanism acquiring, by the background server, a target voiceprint feature which corresponds to S30 the user ID of the voice recognition request to be processed, and acquiring a test voiceprint feature which corresponds to the test voice of the voice recognition request to be processed judging, by the background server according to the target voiceprint feature and the test S40 voiceprint feature, whether the target voiceprint feature and the test voiceprint feature correspond to the same user, and outputting the judging result to the client Receiving and displaying, by the client, the result of the judging FIG.1 Background server 20 Client 10 Feature querying unit Acoustic feature extracting 211 unit 231 Feature processing unit Voice activity detecting unit Client 10 212 232 Model training unit 233 Feature dimensionality Registration voice receiving reducing unit 221 unit 234 Cosine measurement Target voiceprint feature processing unit 222 acquiring unit 235 User recognition Target voiceprint feature Client 10 judging unit 223 storing unit 236 FIG 2
