| Abstract: | In order to have a standard management of opening instruments, we apply the voiceprint recognition system based on GMM-HMM algorithm into the instrument workstation. The uniqueness of voiceprint is utilized to verify the user identity, which realizes unmanned supervision of opening instrument. Based on the voiceprint recognition system, we conducted the experiment of dynamic password speaker verification. The results showed that the false acceptance rate of dynamic password version was lower than 1%, which could avoid the danger of recording playback and assure the system’s reliability. |
