A voice-controlled lighting control system includes a voice-processing device, a lighting control device and a lighting module. The lighting control device is connected to the voice-processing device and the lighting module. The voice-processing device is built in with multiple voice fingerprints and multiple error-tolerant voice fingerprints. During operation, users utter a voice command to the voice-processing device, the voice-processing device compares the received voice command with the voice fingerprints or the error-tolerant voice fingerprints, and sends a control signal to the lighting control device to instruct the lighting module to emit light when finding that the voice command falls within a biometric match threshold of one of the voice fingerprints or the error-tolerant fingerprints. Given the double voice recognition using the voice fingerprints and the error-tolerant voice fingerprints, the precision in recognizing the voice command is enhanced and voice control over lighting can be achieved.
