Sound control door system based on dynamic time warping technology

The invention relates to a sound control door system based on dynamic time warping technology. The sound control door system comprises a sound acquisition module for sound acquisition; the sound acquisition module transmits acquired sound signals to a voice recognition system; the voice recognition system sends a recognition result to a digital signal processing system; the digital signal processing system outputs a door opening signal to an unlocking system; and after the unlocking system receives the signal, an electromagnet generates magnetic attraction, power is provided for an electrical door of a door opening and closing system, and the door opening and closing system opens and closes the door. Huge convenience is brought to life of people, and when the person is inconvenient to use a key to unlock the door, the door can be unlocked only via sound, and great effects can be realized for busy white-collar workers, people with mobility impairments and people who forget to bring keys.
