摘要： An embedded auditory system includes a voice detecting unit for receiving a voice signal as an input and dividing the voice signal into a voice section and a non-voice section; a noise removing unit for removing a noise in the voice section of the voice signal using noise information in the non-voice section of the voice signal; and a keyword spotting unit for extracting a feature vector from the voice signal noise-removed by the noise removing unit and detecting a keyword from the voice section of the voice signal using the feature vector. A method for processing a voice signal includes receiving a voice signal as an input and dividing the voice signal into a voice section and a non-voice section; removing a noise in the voice section of the voice signal using noise information in the non-voice section of the voice signal; and extracting a feature vector from the voice signal noise-removed by the noise removing unit and detecting a keyword from the voice section of the voice signal using the feature vector.
