The acoustic tests of voice were carried out on 46 children with noduli vocales before the treatment and after its completion. Acoustic parameters of voice were compared with the control group of children without voice pathology. The results of the investigation were analysed acoustically. It has been proved that jitter, shimmer, Fo tremor and HNR values significantly differentiate the children with noduli vocales from the children without pathological changes in the larynx. These parameters during treatment tend to approach normal values. Therefore, the acoustic analysis of voice may be used in treatment monitoring.
