11. A terminal, comprising: a non-transitory computer readable medium having instructions stored thereon; and a computer processor coupled to the non-transitory computer readable medium and configured to execute the instructions to: obtain an original audio stream comprising at least one speaker; obtain 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 match 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; use the successfully matched audio stream as an additional audio stream training sample for generating the original voiceprint feature model; and update the original voiceprint feature model to improve a voice recognition capability of a computing device that uses the original voiceprint feature model to identify the at least one speaker.
17. The terminal according to claim 11 , wherein the computer processor is further configured to execute the instructions to: obtain a matching degree between the audio stream of each speaker of the at least one speaker and the original voiceprint feature model according to the audio stream of each speaker of the at least one speaker and the original voiceprint feature model; and select an audio stream corresponding to a matching degree that is the highest and is greater than a preset matching threshold as the successfully matched audio stream.
