Abstract
The present invention provides a random voiceprint certification system comprises a training system, a random cipher generator, and a testing system, which is employed to process training or testing operation for the input raw voice data. In training voice, the training system obtains an appointment voiceprint feature model parameter groups from the input raw voice data. From the appointment voiceprint feature model parameter groups several voiceprint characteristic units are obtained and at least one reference voiceprint password, which is for the testing system to carry out the voice testing operation is built. In processing testing voice, the random cipher generator generates randomly at least one reference voiceprint password from the voiceprint characteristic units of the appointment voiceprint feature model parameter groups to build the random voiceprint cipher lock. The present invention generates randomly one or several reference voiceprint passwords. The random voiceprint certification system is built completely to form the random voiceprint cipher lock. Therefore, the effect of not easy for illegal invasion can be achieved.
