    • PURPOSE: A real time voice activity detecting device and a method thereof are provided to store a voice signal in a plurality of parallel buffers and simultaneously extract two feature information from the stored data. CONSTITUTION: A sound signal buffering unit(120) buffers a digital sound signal of a sound signal obtaining unit(110). A periodicity calculating unit(130) calculates whether the stored sound signal has a periodic feature at a sound frame unit. A voice detection output unit(150) outputs a voice detection signal according to the calculation result. A sample delay storage unit(160) delays and stores the sound signal as much as reference time to output the stored sound signal by synchronization with an output signal of the voice detection output unit.

    • PURPOSE: A device for recognizing a face at real time is provided to access to a plurality pixels at the same time and performs a parallel processing, thereby the device is used generally in application fields using voice processing by higher performance. CONSTITUTION: A down-scaling unit(110) performs down-scaling of inputted image at least one rate. A facial image comparator(130) generates windows per one or more down-scaled images. The facial image comparator obtains facial area reliability of the window image through comparison between an image of the generated window and reference face image. The facial area comparator determines whether the window image is relevant to a facial area.
    • 目的:提供用于实时识别脸部的装置,以同时访问多个像素并执行并行处理,从而通常在使用更高性能的语音处理的应用领域中使用该设备。 构成:缩小单元(110)执行至少一个速率的输入图像的缩小。 面部图像比较器(130)每一个或多个缩小图像生成窗口。 面部图像比较器通过比较生成的窗口的图像和参考面部图像来获得窗口图像的面部区域可靠性。 面部区域比较器确定窗口图像是否与面部区域相关。
