Abstract: Provided are an acoustic sensor and a home appliance system comprising the same. The acoustic sensor comprises a communication unit, a microphone to collect an acoustic signal, a memory to store a failure acoustic signal of a home appliance, and a processor, wherein in response to the acoustic signal, collected by the microphone, corresponding to the failure acoustic signal of the home appliance, the processor transmits the collected acoustic signal, or data corresponding to the collected acoustic signal, to an external server or a terminal. Accordingly, failure of the home appliance may be easily diagnosed.

Abstract: The present invention relates to a method for encoding a voice signal, a method for decoding a voice signal, and anapparatus using the same. The method for encoding the voice signal according to the present invention, includes the steps of: determining an eco-zone in a present frame; allocating bits for the present frame on the basis of the location of the eco-zone; and encoding the present frame using the allocated bits, wherein the step of allocating the bits allocates more bits in the section in which the eco-zone is located than in the section in which the eco-zone is not located.
