You pronounce coherent and clear? Hotel work Xie Na (a pseudonym) recently very depressed, has been nearly six months, their own voice seems to be unable to speak by their own control, some of the words are not always clear sound, as if their own larynx like in the same with their own fight, such as the daily work language “you can not order this dish” sound but seems to be “You should not order this dish”, the meaning is completely opposite. Also, for example, with the subordinates to lay out the work, said “you should always feel that they do not do enough”, issued as if “you are not feel their own”, completely said the wrong meaning. Many of her coworkers thought she had a voice problem and told her to see a doctor. This voice problem has seriously affected her work and life, not to mention her favorite singing. Xena then went to a hospital that specializes in voice disorders to see a doctor. Luckily, a doctor who specializes in voice disorders received her and diagnosed her with “spasmodic dysphonia” after listening to her voice. The doctor told her that this kind of disease is often caused by excessive use of the voice or fatigue after work, especially for professional voice workers, such as teachers, lawyers, hotels, etc. It is especially common in professional voice workers, such as teachers, lawyers, hotel administrators and some government workers. The cause is a “cramp” in the phonatory muscles of the larynx, which can’t be controlled, and after fatigue, leads to slurred speech. This disorder is also differentiated from “stuttering”, which is a slurred, slow and incoherent speech, and spasmodic dysphonia, which is a slurred, but not slow, speech. After a laryngoscopy and an injection of a muscle relaxant into her laryngeal muscles, Xena was able to pronounce words and talk freely again in less than a month. Spasmodic dysphonia is a difficult voice disorder and there is no method in the world that can solve it perfectly. Botox injections are favored by many patients because they can temporarily relieve symptoms without much expense, but they are distressing because of their recurrence. With the development of medicine, more and more treatments are emerging and various surgical methods are multiplying, but still on the way to development, patients are advised to be careful when choosing a procedure.
