Description

LANGUAGE LEARNING SYSTEM AND METHOD USING ABDOMINAL VOCALIZATION SENSE}

The present invention relates to a language learning method and system, and more particularly, to a learner's abdomen, which is attached to a sensor for detecting movement of abdominal muscles, thereby inducing the learner to speak abdominal to improve English speaking ability. The present invention relates to a language learning system and method using utterance detection.

In general, speech is produced by the movement of the muscles of the respiratory, vocal, and articulatory organs through the neural network by language commands from the brain. At this time, the energy source that makes the voice is an aerobic stream coming out of the lungs.

Breathing is one of the most important factors in making voice. Inhalation is mainly done by the diaphragm and exhalation is mainly done by the upper abdomen. Vocalization is based on the relationship between contraction of extrinsic muscles and aerobic activity and includes various vocal functions such as pitch, loudness, and register changes.

Habitual speaking fundamental frequency is most affected by the length and thickness of the vocal cords, as well as by vocalization methods and verbal habits. In particular, in Korean, the frequency is relatively low because most of the vocalization is caused by aerobic flow due to thorax breathing, but in the case of language, the frequency is relatively high because the voice is produced by aerobic flow due to diaphragmatic breathing.

Therefore, in order to be good at language, it is necessary to make vocalization (which is called 'abdominal vocalization') by exhalation caused by the movement of the diaphragm. There is a problem that pronunciation is incorrect because articulation is made by saying ').

In other words, the sound of Korean is a language that requires a small amount of air, so it gives power to the neck with vocal cords, but English is a language that requires a lot of air. For example, if you apply pressure to the neck, the vocal cords will be closed, so the air will not travel much). Therefore, in order to effectively learn English speaking, you need to train to make sounds on the boat, and in order to train and make sounds, learners who do English speaking training need to know whether their sounds give power and make sounds. There is a need.
