The invention provides a voiceprint authentication method and system based on voiceprint recognition, which solves the technical problem that the existing voiceprint authentication method consumes time and labor. The method comprises the following steps of acquiring a voice file of the identity to be identified and a first label of the voice file of the identity to be identified; extracting a first voiceprint feature in a voice file of the identity to be identified; matching the first voiceprint feature with the second voiceprint feature in the preset voiceprint library one by one, and determining a suspect list corresponding to the preset number of second voiceprint features with the highest matching value with the first voiceprint feature; acquiring all sample voices of each suspect in asuspect list in a preset sample library according to the suspect list; determining the sample voice of each suspect which is the same as the first label of the voice file of the identity to be identified according to the preset label included in the sample voice; respectively carrying out phoneme identification on the voice file of the identity to be identified and the sample voice of each suspect, and comparing and determining a suspect corresponding to the voice file of the identity to be identified.
Description
technical field [0001] The invention relates to the field of voiceprint recognition, in particular to a voiceprint identification method and system based on voiceprint recognition. Background technique [0002] In the field of public security and justice, the current voiceprint identification method is that experts manually compare and analyze the voice of the sample and the voice of the sample, and draw a conclusion whether the two voices belong to the same person. The selection of suspects and the collection of speech samples of suspects can only be obtained through police searches. Each case consumes a huge amount of manpower and material resources, and the inspection materials obtained may not necessarily meet the standards. [0003] The invention provides a voiceprint identification method and system based on voiceprint identification to solve the time-consuming and labor-intensive technical problems of the existing voiceprint identification methods.
