PROBLEM TO BE SOLVED: To solve the problems with the prior art that a learner finds it difficult to obtain a sufficiently satisfactory result when learning the pronunciation and identification of English phonemes "l" and "r" and that there is no other choice for the learner but to make such learning only on the limited learning site even if the learner desires to make study. SOLUTION: The system is previously registered therein with the characteristic patterns of the voices "la" and "ra" uttered for several seconds by stressing the portions of the English phoneme "l" and "r" with lapse of time as model patterns and has a function to continuously display the model patterns and the imitation patterns of the learner in real time in compliance with the frequency of the learner in parallel on the same screen and to reproduce the voices of both as required.
