1. A method for updating a voiceprint feature model, comprising: obtaining an original audio stream comprising at least one speaker; obtaining a respective audio stream of each speaker of the at least one speaker in the original audio stream according to a preset speaker segmentation and clustering algorithm; separately matching the respective audio stream of each speaker of the at least one speaker with an original voiceprint feature model to obtain a successfully matched audio stream; using the successfully matched audio stream as an additional audio stream training sample for generating the original voiceprint feature model; and updating the original voiceprint feature model.
