1. A method for providing a voice recognition trigger, comprising the steps of:
calculating a distance change between a device and an object on the basis of proximity information detected by the device; and
determining whether or not the voice recognition trigger of the device is provided with reference to the distance change between the device and the object,
wherein, in the determining step, a time point at which the distance between the device and the object is held constant in a state in which the device is adjacent to the object within a predetermined distance after the device approaches the object at a speed equal to or less than a predetermined speed and the distance between the device and the object gradually shortens from far to near on the basis of proximity information, is determined as a voice recognition start point.
