    • Provided are an apparatus and method for speech segment detection, and a system for speech recognition. The apparatus is equipped with a sound receiver and an image receiver and includes: a lip motion signal detector for detecting a motion region from image frames output from the image receiver, applying lip motion image feature information to the detected motion region, and detecting a lip motion signal; and a speech segment detector for detecting a speech segment using sound frames output from the sound receiver and the lip motion signal detected from the lip motion signal detector. Since lip motion image information is checked in a speech segment detection process, it is possible to prevent dynamic noise from being misrecognized as speech.
    • 提供了用于语音段检测的装置和方法,以及用于语音识别的系统。 该装置配备有声音接收器和图像接收器,包括:唇部运动信号检测器,用于从图像接收器输出的图像帧中检测运动区域,将唇部运动图像特征信息应用于检测到的运动区域,以及检测唇部 运动信号; 以及语音段检测器,用于使用从声音接收机输出的声音和从唇部运动信号检测器检测到的唇部运动信号来检测语音段。 由于在语音段检测处理中检查了唇部运动图像信息,因此可以防止动态噪声被误认为是语音。
