This is the challenge for linguistic pathologists worldwide and their theories.The world notice: Important information on stuttering; publish the root cause and experimental methods of stuttering; a reward of 10,000 USD is offered for refuting this argument . Stuttering has always been an outstanding problem. Many explanations are offered for the etiology of stuttering, but so far there is no medical solution to it. And there can only be one principal cause of a disease, not two. The root cause of stuttering is the error in the use of speech rhythm, this argument can explain stuttering, and is backed up by all the experimental results. Thus, a reward of $10,000 is offered for first anyone who can refute this argument. If no one can refute this argument, it should then proves that this is the only truly effective way to cure stuttering, and the other methods are invalid or incomplete. (This argument has been discussed with most linguistic pathologists. They focus on their own projects without having time to help me. But no one has offered objection, so it can only be published in this way) The reward is valid for 10 days, until 7:00 p.m. on September 12. The readers are requested to forward the message so that more people can hear about the news and participate in it. Experiment on the cause of stuttering: Keywords: explanation of “speech rhythm”: speech rhythm is the language organs coordinating the law of movement in accordance with a certain rhythm. Three scientific experiments verify the impact of the interference of speech rhythm on language. This is a contrast experiment, namely destroying speech rhythm, slowing down speech rhythm, and speeding up speech rhythm. Stone holding method to destroy speech rhythm There is a legendary method – holding a piece of stone in the mouth – of correcting stuttering, but hardly any one uses this method to correct stuttering. It is said this can increase the fluency of language for stutterers. In the actual verification, it is not held in the mouth, but kept between the teeth, so that the mouth cannot be closed. In this way, stuttering will be cured. Because of difference in one word, a majority of orthodontists and stutterers have a misconception and do not use this method. This method has the effect of increasing the linguistic fluency for stutterers, but its principle is to interfere with or destroy the speech rhythm of stutterers. The stutterers using this method can normally use the vocal cords, tongue and lips, but not close the upper/lower jaw. During speech, the stutterer moves the upper and lower jaw to control speech rhythm. In the actual verification, stuttering disappears when stutterers use this method. But it destroys the law of coordination between the language organs and destroys the speech rhythm. This unique role of this method is to verify the result of the destruction of speech rhythm, namely stuttering disappears. Another method is ventriloquism with the similar effect of stone holding method. Slow speech method, delays speech rhythm. This method is currently used globally, and is also the method compatible with speech rhythm controller. The specific way is that a stutterer draws the first sound and slows down the speech. This method is also used to control speech rhythm and to lengthen the duration of speech rhythm Speeding up speech rhythm will trigger stuttering The subjects of experiment speak faster and use heavy accent. In this method, stutterers have a relatively strong reaction, namely the more sufficient and fluent the stutterer has prepared and the faster they speak, the more frequent the stuttering occurs. (Hearing delay feedback device also has the effect of triggering stuttering in general people. The reason is that it extends the response time of language organ in ordinary people, and is consistent with the reasons for the occurrence of stuttering: the response of language organs cannot keep up with the speed and intensity of speech rhythm) Etiology of stuttering: The comprehensive analysis of the above three shows how stuttering occurs. 1. Stuttering occurs when the upper and lower jaw closes or is about to close. Stuttering is accompanied by speech rhythm. There is no stuttering when there is no speech rhythm. In singing, for example, there is no stuttering, as there is no speech rhythm. Or when speech rhythm does not dominate, such as escorting reading. In escorting reading, learning and imitation play the dominant role. Or when no speech rhythm is restrained, such as self-talking. etc. Speech during self-talking is free from the rhythmic stress on the speaker. It is completely arbitrary and relaxed. So when there is no speech rhythm there is no stuttering. 2. Delaying speech rhythm has the role of alleviating stuttering. 3. Speech rhythm is reflected through the rhythm of oral closure. Cause of stuttering. The experiment and analysis show how stuttering occurs. Because stuttering occurs at a single moment, stuttering is caused when the language organ muscle and nerve response cannot keep up with the speed and intensity of speech rhythm, leading to stop and spasm. Or it can be said that because the stutterer’s speech rhythm is too fast, language organs cannot make coordination and cooperation, resulting in a pause. “Speech rhythm controller” invented based on the above principles and its effect. Has the function of controlling speech rhythm. Stuttering does not happen all the time, but at a single moment. The speech rhythm controller has the effect of delaying language (namely delaying the oral closure time. Due to a delay, the language is completed before stuttering begins.) To put it in simple language, the speech rhythm (the time of cooperation among language organs) is extended. This reduces the incidence of stuttering. The function of alleviating stuttering. The early solution is to relax the language organ muscles and nerves of stutterers. First ease the muscle and nerve spasm during stuttering, and then relieve stuttering, such as slow language, breathing method, etc. But when stuttering occurs, it is already too late for immediately relaxing the muscles and nerves. The program is different from the existing programs. This program requires the stutterers to put in efforts to complete language, so that it will form stable, slow speech rhythm, and reduce stuttering. It can also be said that the stuttering person spends a certain amount of time and force on the oral closures, thus giving the other language organs’ muscles and nerves the opportunity for relaxation. Compatible with other effective correction methods. In the early stage, stuttering correction method includes slow speech, breathing method, etc.). The method is compatible with all those. The function of maintaining the language fluency for stutterers. This method has a mandatory effect of correcting stuttering, so you can keep the role of language fluency. Form smooth habits and memory. Through the exercise via “speech rhythm controller”, the stutterer exercises the language organ muscles to complete the fluency of language movements (in layman’s terms, the muscles have the memory of completing specific action), and a language conditioned reflex is established, so that stutterers can successfully complete the same language. How the speech rhythm controller working The speech rhythm controller in correcting stuttering, functions by engaging two magnets in the mouth thus producing magnetism hence resisting the power of oral closure to delay the language compulsively.delaying speech rhythm has the effect of relieving stuttering.
