A biometric fusion electronic lock system contains a central processing module including an image processing unit, a voice processing unit, a digital signal processing unit, a logic processing unit, and an interface control unit. An image capturing module is electrically connected with the central processing module. A voice capturing module is electrically connected with the central processing module. A locking/unlocking module is configured to drive a locking latchbolt to lock or unlock the electronic lock system, and the locking/unlocking module is electrically connected with the central processing module. A storage module is set in a storage media of the electronic lock system so as to store facial features and voiceprint data captured by the image capturing module and the voice capturing module respectively. A liquid-crystal display (LCD) module is electrically connected with an interface control unit of the central processing module.
