Voiceprint recognition method, apparatus and device, and storage medium

A voiceprint recognition device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the following steps when executing the computer program:

• obtaining a target speech information set to be recognized, wherein the target speech information set comprises speech information corresponding to at least one object, and the speech information is obtained after a preprocessing;
• extracting target feature information from the target speech information set by using a preset algorithm, and optimizing the target feature information based on a first loss function to obtain a first voiceprint recognition result;
• obtaining target speech channel information of a target speech channel, wherein the target speech channel information comprises channel noise information, and the target speech channel is configured to transmit the target speech information set;
• extracting target feature vectors in the channel noise information, and optimizing the target feature vectors based on a second loss function to obtain a second voiceprint recognition result;
• and
• fusing the first voiceprint recognition result and the second voiceprint recognition result to determine a final voiceprint recognition result.

A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores computer instructions, and when the computer instructions are run on a computer, the computer is enabled to perform the following steps:

• obtaining a target speech information set to be recognized, wherein the target speech information set comprises speech information corresponding to at least one object, and the speech information is obtained after a preprocessing;
• extracting target feature information from the target speech information set by using a preset algorithm, and optimizing the target feature information based on a first loss function to obtain a first voiceprint recognition result;
• obtaining target speech channel information of a target speech channel, wherein the target speech channel information comprises channel noise information, and the target speech channel is configured to transmit the target speech information set;
• extracting target feature vectors in the channel noise information, and optimizing the target feature vectors based on a second loss function to obtain a second voiceprint recognition result;
• and
• fusing the first voiceprint recognition result and the second voiceprint recognition result to determine a final voiceprint recognition result.
