Title
(EN) Method and device for generating verification content of lip language recognition and related device
(ZH) 唇语识别的验证内容生成方法及相关装置
Abstract
(EN)
The embodiment of the invention discloses a method and device for generating the verification content of lip language recognition. The method and device are suitable for recognizing facial actions inin-vivo body detection. The method includes the steps that a lip language recognition request of a terminal device is acquired, verification request parameters are obtained according to the lip language recognition request, and the number of verification objects needed by lip language recognition verification is determined; recognition objects are selected from a plurality of preset recognition object groups to serve as the verification objects for forming the verification content of lip language recognition, wherein the adjacent verification objects in the verification content belong to different recognition object groups respectively; the verification content is output to a verification interface for lip language recognition, a user of the terminal device is subjected to lip language recognition verification of the verification content. By the adoption of the method and device, the verification content that the adjacent verification objects are different in pronunciation lip shape change can be generated, and the occurrence probability that the lip shape changes are difficult to recognize is reduced, so that the accuracy and convenience of lip language recognition are improved.
