Acoustic analysis of voice in children with noduli vocales

The acoustic tests of voice were carried out on 46 children with noduli voc ales before the treatment and after its completion. Acoustic parameters of voice were compared with the control group of children without voice pathol ogy. The results of the investigation were analysed acoustically. It has be en proved that jitter, shimmer, Fo tremor and HNR values significantly diff erentiate the children with noduli vocales from the children without pathol ogical changes in the larynx. These parameters during treatment tend to app roach normal values. Therefore, the acoustic analysis of voice may be used in treatment monitoring. (C) 2001 Elsevier Science Ireland Ltd.
