Incomplete vocal fold closure may be related to laryngeal nerve paralysis, vocal fold nodules, vocal fold polyps and other diseases, based on active treatment of the primary pathology, the laryngeal muscle function is too strong, the laryngeal muscle function is too weak and the sound quality of the sound anomalies to make the corresponding vocal training to improve.
1. Strong laryngeal muscle function: general training is to ask the patient to lower the jaw, tongue flat, to promote the opening of the pharyngeal cavity and other actions. The most effective is the chewing vocalization therapy. The method is divided into 4 steps: ①chewing food at the same time as the voice; ②chewing with the lips open during the voice; ③chewing the voice after the success of the mastication, increase the words and phrases continue to practice until the establishment of a new voice; ④gradually reduce the chewing activities during the voice.
2. Weakness of laryngeal muscle function: practice breath-holding action repeatedly so that the vocal cords are tightly closed and the chest cavity is fixed while vocalizing.
3. Sound anomalies: If you have poor vocalization due to improper luck, you should establish a mixed chest and abdominal breathing pattern and practice controlling expiratory ability so that expiration is slow and even and the expiratory period is prolonged.
When the vocal folds are found to be incomplete, it is recommended to actively seek medical treatment, and after the examination for a clear diagnosis, we should first actively deal with the original disease, and on this basis, then consider improving the voice by practicing.
