VR Compensated learning pronunciation vr system that shows the movement of the tongue

摘要

The present invention relates to a VR pronunciation correction learning system showing the movement of the tongue, and according to the present invention as described above, the learner sees the chart and recognizes the difference between the pronunciation of Korean vowels/consonants and the pronunciation of English vowels/consonants while It is possible to grasp how similar the vowel pronunciation is to the (standard) vowel pronunciation of a native speaker, and by inducing the pronunciation close or identical to the English vowel, the learner can easily recognize the wrong part of his pronunciation and correct himself. have. Therefore, since the learner can quickly and easily correct the pronunciation, learning can be performed more efficiently, and there is an effect of improving the learning speed and effect. In addition, it is possible to easily check whether the position of the vowel pronunciation the learner makes and the standard vowel pronunciation match, so that the learner can correct his or her pronunciation more precisely, which is very helpful. It had a flaw and was unable to give exercise to regenerate memory and brain frequently during study, and some people solved uncomfortable problems such as having to study while covering the meaning of words with a cover note. That is, the present invention includes a storage means for storing a chart in which the movement of the tongue is visualized according to the resonance point of the formant frequency among the resonance points of the Korean vowel/consonant pronunciation and the English vowel/consonant pronunciation in an English vocabulary book; VR display means for displaying the chart; A voice input means for receiving a voice from a learner; Analysis/extraction means for analyzing the input voice and extracting a frequency band; And a control means for displaying the extracted resonance point at a corresponding position in the chart; wherein the storage means visualizes the resonance point of the formant frequency among the resonance points of the Korean consonant pronunciation and English consonant pronunciation in a peak form. The chart is stored, and the analysis/extraction means is composed of a visual English pronunciation correction system, characterized in that the voice inputted by the voice input means is analyzed through LPC peak waveform analysis and the movement of the tongue is displayed on the VR display means. . Accordingly, according to the present invention, as described above, according to the present invention, the learner sees the chart and recognizes the difference between the pronunciation of Korean vowels/consonants and the pronunciation of English vowels/consonants, while the pronunciation of their English vowels is different from the (standard) vowel pronunciation of a native speaker. It is possible to grasp the degree of similarity, and by inducing close or identical pronunciation with English vowels, the learner can easily recognize the wrong part of his pronunciation and correct himself. Therefore, since the learner can quickly and easily correct the pronunciation, learning can be performed more efficiently, and there is an effect of improving the learning speed and effect. In addition, it is possible to easily check whether the position of the vowel pronunciation the learner makes and the standard vowel pronunciation match, so that the learner can correct his or her pronunciation more precisely, which is very helpful. It had a flaw and was unable to give exercise to regenerate memory and brain frequently during study, and some people had the effect of solving uncomfortable problems such as having to study while covering the meaning of words with a cover note.
