The most common defects in children’s voices

A poor speaking voice usually also means a poor singing voice. Voice damage in children may already appear during the elementary school age. Most of the damage is caused by incorrect tone formation and incorrect use of the voice, as mentioned at the beginning of this lesson.
An aspirated tone (a voice with unregulated breath mixed in) is considered to be the most widely spread vocal fault, that is caused by a forcefully formed voice. The created tension prevents the vocal cords from working freely and leads to incomplete vocal cord closure followed by an excessive exhalation.
This voice defect is very easily remedied with correct voice instruction.
Vocal cord nodules can occur through uncontrolled shouting, most often on playgrounds or in choirs with poor voice instruction. Surgery is not always necessary. If found in time they can be removed through correct vocal technique exercises.
"Sudden off key singing" occurs primarily during stage fright. Children who otherwise intonate accurately begin to sing off key. This problem is usually seen in shy or timid children or in children who have overly high expectations of themselves. For shy and timid children, this problem should subside by itself as they grow older. The only option for children in the latter category is to work even harder. If they gain self-confidence and feel that they have "something to offer", their uncontrolled stage fright will miraculously disappear.
Obstacles in the resonators (nasal cavities) are a fairly common problem. When the child's voice sounds like it is affected by a cold, the problem is most likely caused by an enlarged adenoid. Removal of an enlarged adenoid is a minor procedure today.
Pronunciation problems, such as sharp or dull sibilants, incorrect pronunciation of vowels (L, etc.) and other such problems can be eliminated through speech therapy.
