principle    to Project Many stutterers have a crying need in a simple, labor-saving and really effective correction method, in which case, the invention a favorable for resolving such problems. Why I called the orthotics as a correction method? Stutters may simulate such use mode as a method after a period of experience and practice. Such method is featured with a method of almost normal speed rather than slow talking; however, in which case, a stutterer may practice fluent talking, and it plays a role of overcoming even though he or she hunches a stammer.  Through years of verification and research, the researcher has invented the language rhythm controller. The essence of stutter is spasm because the muscular and nervous reaction of the language organ of the stutterer cannot follow the speed and intensification of language rhythm. All the existing effective methods (rhythm method, pronunciation method, breathing relaxation method, etc.) play a role of relaxing, easing muscle and nerve. However, after stutter correction, stutter recurs for all cases without exception. The reason for this is that these methods correct stutter by relaxing, easing dominated by stutterers themselves (self-awareness). However, this cannot stop completely the muscular spasm occurring to a stutter when he/she speaks. Only by making forced correction through pertinent equipment, can spasm occurrence in stutter be stopped and thus the purpose of stutter correction can be achieved.      Stutter correction not only requires forced stop of “stutter”, but also needs a long-lasting language fluency habit and a correct language rhythm. Only in this way, can stutter correction be successful.  The characteristics of this language rhythm controller are: not only being able to control the language rhythm of a stutter with a forced stutter correction effect, but also being compatible with all effective autonomous stutter correction methods simultaneously to maintain a long-lasting correction effect. Especially, a stutter will feel a fluent effect after physical use and experiencing. The stubborn stutter in the past and those words where stutter occurs frequently, etc. will disappear gradually and no language quality in speaking (pronunciation and enunciation) is influenced at all. The reason for this phenomenon is because the language rhythm controller can change the force field formed by stutter. Therefore, the places where seizure frequently occurs disappear to become fluent gradually.   When such correction lasts for some time and becomes a habit, the effect of stutter correction can be achieved.      This invention verifies the effectiveness of the correcting device and its theory through three experiments.     ① Damage or interfere with the language rhythm of a stutter and thus the stutter of a stutter will disappear or be mitigated. (This can be realized through the method of putting a stone in the mouth being well-known in history. The specific practice is let a speaker bite a piece of stone between his/her upper and lower teeth in his/her mouth. The speaker will lose the language rhythm due to his/her mouth being unable to open and close and stutter will disappear likewise). This experiment proves the role of language rhythm in correcting stutter.      ② By interfering with the language rhythm of a normal speaker stutter will appear. (The specific practice is that when the magnetic poles of the language rhythm controller are changed from same poles opposing to each other to different poles opposing to each other, stutter will occur to a normal speaker). This is proof by contradiction. Similarly, magnetic force reversal has a role of forced stutter correction. This experiment simulates the process of stutter occurrence and reproduces a reverse experiment for stutter.      ③ The language rhythm controller in this invention can almost be compatible with all autonomous stutter correction methods (such as rhythm method, pronunciation method, breathing method, etc.) (through being compatible with all effective methods and intensifying and lasting the correction effect, the stutter correction effectiveness of this invention is verified).      The method to verify this invention is popular and easy to understand. Anyone can understand the principle through the simple verifying method.      Through the above three points, the effectiveness of the language rhythm correction device can be verified. Here are the advantages:           ① The reason for failure in stutter correction in the past is due to lack of persistence and forcibility and correction effect consolidation. (Stutter correction requires a lasting correction process).           ② Early stutter is not corrected in the initial phase and the best correction opportunity is missed. (Stutter correction in the children period is crucial, which is the best period for stutter correction).            ③ The autonomous stutter correction method is complicated and hard to last for a long time. In comparison, this invention is simple, convenient, long-lasting and very easy to operate.                                   Language Rhythm Controller                                     Abstract image The utility model claims a language rhythm controller used for correct stammer, comprising a palate piece and a mandible piece. The palate piece comprises a palate magnetic sheet adhered to the palate inner wall of the mouth and a palate alloy fixing frame fixed on the palate magnetic sheet. The mandible piece comprises a mandible magnetic sheet adhered to the inner wall of the mandible of the mouth and a mandible alloy fixing frame fixed on the mandible magnetic sheet; the mandible alloy fixing frame and the palate alloy fixing frame are fixed with the external wall of the tooth to ensure that the palate magnetic sheet and the mandible magnetic sheet are adhered to the palate and mandible inner walls of the mouth stably. The palate magnetic sheet is opposite to the mandible magnetic sheet; the opposite face of the palate magnetic sheet and the mandible magnetic sheet is the exclusive property. Under the effect of the repulsion of palate magnetic sheet and mandible magnetic sheet, the mouth must overcome a fixing resistance when closing so as to delay the language speed, ensure the mouth closing action as a tone, form a stable language rhythm and achieve the effect of language rhythm control, forming health language rhythm and correctingstammer.
