What are the people who use their voices professionally? People generally think that professional voice users refer to singers, but in fact, there are two types of professional voice users, one is singing-based such as: bass, alto, soprano, opera, beautiful voice and other singing people; the other is speaking-based such as: actors, announcers, hosts, translators, dubbers, journalists and other voice users. What does the examination of professional voice users include? 1.Psychoacoustic examination: It is an analysis method to determine the subjective impression of the patient’s voice based on the objective scale. 2.Voice acoustic examination: It is an examination to determine the overall vocal status of the patient based on the indicators of vocal cord movement characteristics. 3. Airflow dynamics: The voice is produced by the air that is inhaled and is about to enter the lungs during respiration, causing the vocal folds to vibrate through the larynx. The air inhaled is the driving force of the voice, so the airflow dynamics test is a necessary test to check whether there is any obstacle in the voice mechanism. 4.Vocal range test: The vocal range test is a test that examines the patient’s pronunciation of the 5th tone scale in the pitch apprehension and articulation pattern. It is a test to understand the state of articulation pattern and articulatory function by detecting the high and low tones and intensity of the pitch shift of chest, head and falsetto. 5.Laryngeal stroboscopic examination: through clear impact, it is an effective examination method that can visually see the condition of vocal fold vibration and the presence of disease when pronouncing. 6.Ultra-high-speed vocal fold filming examination: High-speed video image examination can not only clearly observe the non-periodic vocal fold vibration and vocal fold spasm at the beginning and end of voice, but also detect the irregularity of vibration and the changing condition and tension of vocal fold muscles. 7.Airflow dynamics multi-source measuring instrument: It is the first equipment developed by Yisong in the world to examine the muscles related to articulation and the respiratory voice itself from multiple angles. Unlike the original method of subjective evaluation, it can objectively and accurately examine the voices of vocal professionals and practical music professionals. 8. End-selective speech voice assessment 9. Vocal pattern end-selective examination The contents of the voice examination for the first category of people who mainly sing and the second category of people who mainly speak professionally are different, and the points to be evaluated in the report are also different. The main difference lies in the seventh point of the PKE, which is an independent test developed by Yisong that is designed for the first category of professionals who mainly sing, and is aimed at the unreasonable state of the muscles, breathing, and posture of the vocal cords. Many patients may ask why I need to have a checkup when I can just come here for treatment? In fact, it is not true. The human articulatory organ has a very complex function. The whole articulatory system includes power organs, vibratory organs, resonance organs and phonation organs, among which the vibratory organs, mainly the vocal folds, are the most important in the formation of the voice. The respiratory organ is the power organ, which vibrates the vocal folds by exhaling air from the lungs. The resonance organs include the thoracic cavity, pharyngeal cavity, oral cavity, nose and sinuses, etc. The changes in their shape and size can form a unique tone. The organs of articulation include the mouth, tongue, lips, teeth and palate, which form various vowels and consonants. This shows the complexity of the articulatory organs, and without a series of examinations to determine the treatment plan, there is no way to carry out post-treatment. For professional voice users, the good or bad of voice determines the development of career. We warmly suggest you to practice your voice under the guidance of professional teachers and master the scientific method of voice practice so as to prevent voice diseases caused by improper use of voice. The correct breathing movement is the basis of pronunciation, and the coordinated operation of inhalation and exhalation should be achieved when singing in order to make the singing sound smooth, natural and beautiful. Every singer should select works suitable for him or her according to his or her actual situation, so that he or she can perform at a high level and give popular singing. For voice health care, a good diet, adequate sleep and scientific methods of using voice are the most important things.
