Abstract: 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.

Abstract: An image processing system for displaying pixel data on a screen performs a binary-encoding method using error diffusion with edge enhancement. In the method for binary-encoding the image data, pixels to be binary-encoded are divided into normal and edge regions, and the pixel data is binary-encoded in accordance with the divided regions. By using the method, bars on the display screen which are unpleasant to the eye can be removed and an image with good edge sharpness can be obtained.
