An intelligent illumination speech recognition algorithm based on voiceprint recognition is proposed.The short-time energy and short-term average zero-crossing rate are used to judge the voice signal. The method based on Gaussian mixture model-universal background model（ GMM-UBM） is used to determine the identity of the controller. The method based on the dynamic time warping（ DTW） is used to identify semantics. Through the establishment of adaptive real-time speech training sample library with multiple identity persons and multiple voice commands

the logarithm likelihood method and vector cumulative distance method are used to realize voice controller identification and voice signal semantic recognition. The simulation results show that the algorithm can quickly and accurately determine and identify the identity and semantics of intelligent lighting voice signal.
