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.
