Voiceprint recognition method for speech information set optimization
A recently granted patent (Publication Number: US12002473B2) discloses a voiceprint recognition method that involves obtaining target speech information, extracting target feature information using a preset algorithm, optimizing the feature information based on loss functions, extracting target feature vectors from channel noise information, and fusing the results to determine a final voiceprint recognition result. The method includes storing speech information in a blockchain, calculating similarity matrices, and performing discrete cosine transform to obtain target feature information. Additionally, the method involves extracting feature vectors, calculating mean square error matrix, and fusing recognition results using a specific formula.
Furthermore, the patent also covers a voiceprint recognition device and a non-transitory computer-readable storage medium that enable the implementation of the voiceprint recognition method. The device includes a memory, processor, and a computer program that executes steps such as obtaining speech information, extracting feature information, optimizing based on loss functions, extracting feature vectors from noise information, and fusing results. The computer-readable storage medium stores instructions for performing similar steps, including calculating similarity matrices, transforming feature information, and calculating mean square error matrix. Overall, the patent provides a detailed method and system for voiceprint recognition, incorporating advanced algorithms and techniques to enhance accuracy and efficiency in recognizing voiceprints.
