1. A voice control system for an automatic door, the voice control system comprising:
a sound detection device configured to detect a sound signal of a sound source;
a storage device comprising a voiceprint database, wherein the voiceprint database comprises a plurality of reference voiceprint features;
a first determination circuit electrically connected to the storage device and the sound detection device, wherein the first determination circuit is configured to analyze a voiceprint feature of the sound signal and compare the voiceprint feature with the reference voiceprint features, so as to determine whether or not the voiceprint feature matches one of the reference voiceprint features;
a second determination circuit electrically connected to the first determination circuit, wherein the second determination circuit is configured to determine whether or not a velocity of the sound source falls within a reference speed range according to a frequency variation of the sound signal that matches at least one of the reference voiceprint features; and
a control circuit electrically connected to the second determination circuit, wherein, in response to the velocity of the sound source within the reference speed range, the control circuit controls the automatic door to be in an open state.
