METHOD AND DEVICE FOR PROCESSING SOUND SIGNAL

摘要

Disclosed is a method for processing a sound signal. A method for processing a sound signal includes: a step of receiving a sound signal from the outside of a device, a step of converting the sound signal into a first frequency domain signal, a step of determining whether the sound signal is a voice signal by using the first frequency domain signal obtained by the conversion, a step of converting the first frequency domain signal into a second frequency domain based on the determination, and a step of recognizing the sound signal by using the second frequency domain signal obtained by the conversion. So, the operation of processing the sound signal can be efficiently carried out.
