Development of a foreign language short sentence prompt translation practice system base on a fuzzified determination procedure of the material

我们开发了一个基于英语句子记忆的外语口语练习系统学习任务选择的模糊化程序。在系统中，材料中的学习任务基本上是随机选择的，但实际上可以准随机地进行，通过模糊化运算将所有材料共有的几个属性的值与学生的值相匹配。利用这种方法，我们开发了一个适合学生的任务很容易选择的系统。另一方面，为了配合实际学习，我们采用了限时同步的录音设备。实际上，只要他/她想说，就应该尽快说出来。上述录音设备可以帮助学生在实际的口语环境中做到这一点。

We developed a fuzzified procedure of learning task selection in a foreign speaking practice system based on English sentence memorization. In the system, a learning task in a material is basically selected at random, but actually it can be conducted at quasi-random in a manner that several properties common to the all material, each property value is matched to the value of the student by a fuzzified operation. With the method, we developed a system in which a task fitting to the student is easily selected. On the other hand, in order to cope with the actual learning, we adopted an audio-recording facility with time restriction and synchronized method. Actually speaking is needed to be done as soon as he/she thinks to do that. The said audio-recording facility helps a student to do that in an actual speaking situation.
