Abstract
Electrolaryngographic recordings were made of spoken and sung voices of 256 trained and untrained singers aged 8-18. The authors examined measures of Larynx Closed Quotient (CQ) over a sung scale and spoken passage and related them to the parameters of sex, development and vocal training.
A positive correlation between CQ and development was found for both the singing and spoken voices of boys. Girls, however, showed a negative correlation between sung CQ and development, but exhibited no correlation between spoken CQ and vocal development. Trained singers in both sexes exhibited slightly lowered mean sung CQ, with a reduced range of values and lower standard deviation, possibly demonstrating greater control over the vocal mechanism. It is proposed that this demonstration of qnuntifiable vocal differences could form the basis of a biofeedback tool for pedagogoy and vocal health monitoring.
