    • 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。

    • Glyphs, symbols, or non-symbols are selected and become a “search term.” The search term is normalized and then depicted upon a grid for marking. Marked search term areas may be measured from a center point. The marks and measurements can be converted in to a distance map. For reference material loaded into a master database, each distance map may be given a unique code, which may correspond to a Unicode value. An end user may find new material to search, select a new search term and enter the search term into a disclosed system. The target term can be converted into distance maps and then matched with the distance maps of the master database. The pixels or extrapolated geometry of the search term can be used to match system documents that do not have an associated code.
    • 选择字形,符号或非符号,并成为“搜索词”。搜索项被归一化,然后在网格上进行标记。 标记的搜索项区域可以从中心点测量。 标记和测量可以转换为距离图。 对于加载到主数据库中的参考资料,每个距离图可以被给予唯一的代码,这可以对应于Unicode值。 最终用户可以找到要搜索的新材料,选择新的搜索词并将搜索词输入到公开的系统中。 目标项可以转换为距离图,然后与主数据库的距离图匹配。 搜索项的像素或外推几何可用于匹配没有关联代码的系统文档。
