Abstract
(EN)
A verification content generation method and apparatus for lip-language recognition. The method comprises: acquiring a lip-language recognition request of a terminal device, and obtaining a verification request parameter according to the lip-language recognition request (S401); determining the number of verification objects required for lip-language recognition verification, and selecting recognition objects from multiple pre-set recognition object groups as the verification objects to form verification content for lip-language recognition, wherein adjacent verification objects in the verification content respectively belong to different recognition object groups (S402); and outputting the verification content to a verification interface for lip-language recognition, and performing lip-language recognition verification on a user of the terminal device by using the verification content (S403). By means of the method, verification content where adjacent verification objects have different pronunciation lip changes can be generated, thereby improving the accuracy and convenience of lip-language recognition.

L'invention concerne un procédé et un appareil de génération de contenu de vérification pour la reconnaissance du langage labial. Le procédé comprend les étapes suivantes : acquisition d'une demande de reconnaissance de langage labial d'un dispositif terminal et obtention d'un paramètre de demande de vérification en fonction de la demande de reconnaissance de langage labial (S401) ; détermination du nombre d'objets de vérification exigés pour une vérification de reconnaissance de langage labial et sélection d'objets de reconnaissance à partir de multiples groupes d'objets de reconnaissance prédéfinis en tant qu'objets de vérification pour former un contenu de vérification pour une reconnaissance de langage labial, des objets de vérification adjacents dans le contenu de vérification appartenant respectivement à des groupes d'objets de reconnaissance différents (S402) ; et délivrance du contenu de vérification à une interface de vérification pour une reconnaissance de langage labial, et réalisation d'une vérification de reconnaissance de langage labial sur un utilisateur du dispositif terminal en utilisant le contenu de vérification (S403). Le procédé permet de générer un contenu de vérification dans lequel des objets de vérification adjacents ont des changements labiaux de prononciation différents, améliorant ainsi la précision et la commodité de la reconnaissance du langage labial.

一种唇语识别的验证内容生成方法和装置,该方法包括:获取终端设备的唇语识别请求,根据唇语识别请求得到验证请求参数(S401);确定唇语识别验证所需的验证对象的数量,并从预置的多个识别对象分组中选取识别对象作为验证对象组成唇语识别的验证内容,其中,验证内容中相邻的验证对象分别属于不同的识别对象分组(S402);将该验证内容输出到唇语识别的验证界面,使用该验证内容对终端设备的用户进行唇语识别验证(S403)。该方法能够生成相邻验证对象发音唇形变化不同的验证内容,提高了唇语识别的准确率和方便性。
