    • A method and apparatus for synthesizing speech or facial movements to match selected speech sequences. A videotape of an arbitrary text sequence is obtained including a plurality of images of a user speaking various sequences. Video images corresponding to specific spoken phonemes are obtained. A video frame is digitized from that sequence which represents the extreme of mouth motion and shape. This is used to create a database of images of different facial positions relative to spoken phonemes and diphthongs. An audio speech sequence is then used as the element to which a video sequence will be matched. The audio sequence is analyzed to determine spoken phoneme sequences and relative timings. The database is used to obtain images for each of these phonemes and these times, and morphing techniques are used to create transitions between the images. Different parts of the images can be processed in different ways to make a more realistic speech pattern.
    • 一种用于合成语音或面部动作以匹配所选语音序列的方法和装置。 获得任意文本序列的录像带,其包括说出各种序列的用户的多个图像。 获得与特定语音对应的视频图像。 从该序列数字化视频帧,其表示嘴部运动和形状的极端。 这是用来创建一个相对于口头音素和双声道的不同面部位置的图像数据库。 然后,音频语音序列被用作视频序列将被匹配的元素。 分析音频序列以确定口语音素序列和相对定时。 数据库用于获取每个这些音素和这些时间的图像,并使用变形技术来创建图像之间的转换。 图像的不同部分可以以不同的方式进行处理,以形成更逼真的语音模式。
