By enabling the trainee with language disorder and the instructor (therapist) to feel the spoken pronunciation with vibrations as well as a sound, it is possible to effectively conduct pronunciation training and correction by matching the sound and the vibrations of the spoken pronunciation.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pronunciation correction apparatus and method using a chair having a vibration speaker,

More specifically, the present invention relates to a pronunciation correcting apparatus, and more particularly, to a vibration correcting apparatus that attaches a vibrating speaker to a chair, generates vibrations corresponding to pronunciations of an educator and a pronouncing person through a vibrating speaker, The present invention relates to a pronunciation correcting apparatus and method using a chair having a vibrating speaker for transmitting a vibration corresponding to a pronunciation to a learner who is a target of correction and learning pronunciation of words and spoken words.

In general, language is a symbolic system that humans use to communicate. There may be many complementary alternatives to communication besides speech or writing, but human communication is mostly through spoken or written language. It can also be a handwritten or handwritten language used by the deaf. The language includes not only a symbolic system for spoken language, but also an octopus and a language system.

Spoken language is a language that human beings can hear through their ears as a means of communicating through a pronunciation agency. For normal speech, the pronunciation agencies such as breathing, vocal cords, tongue, lips, and research dogs should perform normal functions.

Generally speaking, the most important thing to communicate properly is to understand what you are listening to and what you are talking about.

However, children with speech impairments such as children with developmental disabilities and hearing impaired people do not listen to or listen to the other person's words, so they can not pronounce or pronounce incorrect words or spoken words.

The methods of treating (or "learning") those with language impairments include the use of dioceses to learn words and expand words, diagonal learning methods, professional counseling through professional counseling and learning, And a vibration learning method in which the vibration is transmitted and treated.

However, in the case of the parody learning method, it is not possible to recognize the actual pronunciation of the word by the language disabled person mainly in the word learning using the parish. In the case of the vibration learning method, the vibration corresponding to the pronunciation is felt through the hand, There was a problem that the learning could be slowed down. In addition, the expert counseling method has a problem that the learner does not listen or listen, so that it is difficult to transmit the pronunciation to be learned even if it is a professional.
