Method for updating voiceprint feature model and terminal

摘要

A method for updating a voiceprint feature model and a terminal. The method comprises: obtaining an original audio stream comprising at least one speaker (S101); obtaining the respective audio stream of each speaker in the at least one speaker in the original audio stream according to a preset speaker segmentation and clustering algorithm (S102); matching the respective audio stream of each speaker in the at least one speaker with an original voiceprint feature model, so as to obtain the successfully-matched audio stream (S103); and using the successfully-matched audio stream as an additional audio stream training sample used for generating the original voiceprint feature model, and updating the original voiceprint feature model (S104). According to the present invention, the valid audio stream during a conversation process is adaptively extracted and used as the additional audio stream training sample, and the additional audio stream training sample is used for dynamically correcting the original voiceprint feature model, thus achieving a purpose of improving the precision of the voiceprint feature model and the accuracy of recognition under the premise of high practicability.
