Abstract

The invention provides a speaker identification method and system, and belongs to the technical field of speaker identification. The method comprises the steps of analyzing voice signals by using a confirmation network, extracting voiceprint features of the voice signals, and confirming whether the voice signals are from the same speaker or not; and analyzing the voiceprint features of the voice signals by using an identification network, and identifying the identity of a speaker of the voice signals. According to the method, specific voiceprint features of the speaker are extracted, channel noise interference is reduced, and the identification accuracy of the speaker is improved; the speaker confirmation network and the speaker identification network can assist each other by adopting a multi-task learning form, so that the confirmation effect and the identification effect are improved; a human brain thinking mode is simulated by combining a speaker confirmation technology, and identification is carried out by combining the confirmation technology under the condition that the number of speakers is large and the identification difficulty is high; and through the simulation application of the human brain thinking model, the intelligence of the algorithm is improved, and the identification ability of the model under the condition of high difficulty is enhanced.

Description

Technical field [0001] The present invention relates to the field of speaker recognition, and in particular to a speaker recognition method and system that improves speaker recognition accuracy. Background technique [0002] The speaker identifies a wide application prospect, which can be widely used in the fields of security, social security, and criminal investigation. The speaker identifies the confirmation and speaker recognition of two major technologies. The speaker confirms that it refers to the speech to confirm whether the current speaker is a registered person who has been registered, or determines whether the two speech comes from the same person. The speaker confirmed that it was a class of classification technology. The speaker recognition is a multi-class classification technology to discriminate the identity of the speaker according to people's voice. [0003] The implementation method of speaker recognition is usually a feature extraction model to extract speaker'...
