The invention provides a voiceprint recognition method and device, and belongs to the field of voice recognition. The voiceprint recognition method includes the following steps of collecting voice, preprocessing voice, extracting voiceprint feature value and comparing patterns, wherein the voiceprint feature value of a speaker is compared with the voiceprint feature value prestored in a pattern library; if the voiceprint feature value is the same as the prestored voiceprint feature value, a voice command is executed, and if the voiceprint feature value is different from the prestored voiceprint feature value, the voice collection step is executed. The voiceprint recognition method and device are applied to a vehicle-mounted keyless system, voice recognition is adopted, door closing or opening is confirmed through distance operation, the operation is convenient and fast to conduct, meanwhile it is guaranteed that only an owner can open or close a door due to the fact that identify confirmation is conducted through voiceprint recognition, and safety of automobiles is facilitated.
