The reason why humans can develop language is primarily because the vocal cords can resonate and produce sound under the action of airflow. This also involves the combined action of the oral cavity and teeth to form language. If one excessively uses their voice over a long period, inflammation may occur at the junction of the anterior and middle third of the vocal cords, where the frequency of sound vibration is relatively high. This can easily lead to the formation of small nodules, commonly known as singer's nodules. This condition often occurs in people whose professions involve heavy voice use, such as teachers, musicians, kindergarten teachers, salespeople, and so on. If these vocal cord nodules are managed with voice rest and by avoiding spicy and irritant foods, recovery is quite likely.
