![]() In the phonation stage, the subglottal pressure must reach a certain point to set the vocal folds into a vibratory position. ![]() A person who has contracted the coronavirus not only may experience shortness of breath but may also have difficulty exhaling, which results in the lack of energy to produce sound and hence a disruption in the speech production cycle. In the respiratory stage, the force that is needed for generating sound is provided by the air expelled from the lungs. Voice production is a 3-stage process: Respiration, phonation, and resonating system. ![]() 2 “Respiratory tract infections affect the same system and structure that are used for voice production.” 3 Although the primary function of the respiratory tract is to provide oxygen to the body, its secondary and equally important function is to provide energy and produce phonation for the purpose of speech communication Symptoms of acute upper respiratory tract infections, such as cough, sore throat, rhinorrhea and sneezing, as well as digestion symptoms, like vomiting, are associated with mild cases of this disease, and symptoms like pneumonia and acute respiratory distress are primarily seen in severe and critical cases, respectively. As indicated by Rothan and Byrareddy, 1 COVID-19 principally affects the respiratory system, and people infected with the disease may experience pneumonia and acute respiratory distress syndrome. Since then, with more than 17,000,000 confirmed cases worldwide and counting, coronavirus has become one of the most challenging issues with which the world is faced. In early March 2020, the World Health Organization (WHO) declared COVID-19 as a pandemic.
