The first mention of the relationship of voice disorders with the mental state of a person was made back in 1890 by F.E. Ingals, who viewed aphonia as a form of hysteria. R. Jane in 1920. in his work "The main symptoms of hysteria" he considered "sudden paralysis or loss of voice" as one of the "salutary ways out of the situation", when patients can show "a perverse attitude towards reality through the demonstration of their incapacity." D.K. Wilson (1990) notes the influence of a person's mental state on such parameters of a voice as loudness, pitch, pitch variation and voice quality. Curtis (1967) considered one of the causes of voice disorders in children to be poor adaptability to the environment and poor relationships between parents and children, lack of mutual understanding in interpersonal contacts. According to Andrews (1988), when testing patients with vocal disorders, a significant increase in the so-called cases of "conflict in expressing one's feelings through speech" was found.
