    摘要： Disclosed is an artificial intelligence apparatus for recognizing a plurality of wake-up words, including a microphone, a memory configured to store a first wake-up word recognition engine, a communication interface configured to communicate with a server storing a second wake-up word recognition engine, and a processor configured to acquire an audio signal through the microphone, generate a pre-processed audio signal from the acquired audio signal, extract a voice interval from the generated pre-processed audio signal, set a wake-up word recognition interval comprising the extracted voice interval and a buffer interval corresponding to the extracted voice interval in the generated pre-processed audio signal, wherein the wake-up word recognition interval is an interval used for recognizing wake-up words, and transmit the set wake-up recognition interval in the generated pre-processed audio signal to the first wake-up word recognition engine and the second wake-up word recognition engine.

    摘要： A laundry drying machine includes: a cabinet, a drum disposed inside the cabinet and configured to accommodate a target object, a driving unit configured to rotate the drum, and an electric field generator spaced apart from the drum and configured to generate an electric field inside the drum. The drum includes: a drum body having a cylindrical shape and accommodating the target object, a ground electrode that is in contact with an outer circumferential surface of the drum body, and a support roller that is in contact with the outer circumferential surface and that is configured to, based on the drum body rotating, support the drum body in a direction of the ground electrode, and a shortest distance between a central axis of the support roller and the ground electrode is less than a sum of a diameter of the drum body and a radius of the support roller.

    摘要： The present disclosure relates to a laundry treatment machine. A laundry treatment machine according to an embodiment of the present disclosure includes: an inverter converting a direct current (DC) voltage from a converter into an alternating current (AC) voltage based on a switching operation and outputting the converted AC voltage to a circulation pump motor; and a controller to control a speed of the circulation pump motor to be increased before a time point at which a speed of a washing tub motor increases. Accordingly, the washing tub motor and the circulation pump motor can be operated in synchronization with each other. As a result, it is possible to improve washing power based on circulation pumping during washing.
