    • The present invention provides a spoken document retrieval system capable of high-speed and high-accuracy retrieval of where a user-specified keyword is uttered from spoken documents, even if the spoken documents are large in amount. Candidate periods are narrowed down in advance on the basis of a sequence of subwords generated from a keyword, and then the count values of the candidate periods containing the subwords are each calculated by adding up certain values. Through such simple process, the candidate periods are prioritized and then selected as retrieved results. In addition, the sequence of subwords generated from the keyword is complemented assuming that speech recognition errors occur, and then, candidate period generation and selection are performed on the basis of the complemented sequence of subwords.
    • 本发明提供了一种口语文献检索系统,即使说出的文件数量大,能够从口头文件发出用户指定的关键字的高速和高精度检索。 基于从关键字生成的子序列,预先将候选时间缩小,然后通过将特定值相加来计算包含子词的候选时段的计数值。 通过这样简单的过程,优先考虑候选周期,然后将其选为检索结果。 此外,假设发生语音识别错误,补充从关键字生成的子词的序列,然后基于补充的子词序列执行候选句点的生成和选择。

    • A sign language telephone device is offered which enables an aurally handicapped person who uses the sign language to converse with a normal person at a distant place who does not know the sign language. The sign language telephone device is placed on the side of the aurally handicapped person, and hand gestures of the sign language inputted from a sign language input means are recognized as the sign language, and the recognized sign language is translated to Japanese. The translated Japanese word train is converted to synthesized voices and it is transmitted to a videophone on the side of a normal person. The voices from the videophone are recognized, and the recognized Japanese is translated to the sign language to generate sign language animations and they are displayed on the screen of a TV set on the side of the aurally handicapped person. According to the present invention, it is made possible for an aurally handicapped person to have conversation easily with a normal person at a distant place who does not know the sign language through an existing network.
    • 提供了一种手语电话设备,使得使用手语的听力障碍者能够与不知道手语的远方的普通人交谈。 手语电话装置被放置在听觉障碍者的一侧,并且从手语输入装置输入的手语的手势被识别为手语,并且将识别的手语翻译成日语。 被翻译的日语单词列表被转换为合成语音,并且被传送到正常人的一侧的视频电话。 来自视频电话的声音被识别,并且认可的日语被翻译成手语以产生手语动画,并且它们被显示在听觉残疾人一侧的电视机的屏幕上。 根据本发明,通过现有的网络,使听觉障碍的人能够与不熟悉手语的远方的普通人容易地进行对话。

    • A continuous sign-language recognition apparatus and input apparatus which employ expressions of template patterns of sign-language word as well as the template patterns of sign-language word to realize high speed and highly accurate sign-language recognition. Each of component patterns constituting a template pattern of a sign-language word is expressed by a feature vector representing the pattern when the pattern is a static pattern, or by a time-series pattern of a feature vector when the pattern is a dynamic pattern. Also, using the template patterns of sign-language word, different matching methods are applied to the static and dynamic patterns for recognizing each component pattern, and the respective results are integrated on the basis of a temporal overlap of the respective component patterns to continuously recognize sign-language words.
