The validity and reliability of the Wilson Voice Profile System (WVPS) was assessed by using taped matched voice samples of groups of 20 previously evaluated voice disordered and 20 normal children. A group of 11 trained listener-judges evaluated these vocal samples.

The WVPS results for differentiating normal from abnormal voiced children were similar to those obtained by previous independent voice studies. This suggests voice-disorder identification validity in the WVPS.

Additional results indicated that the WVPS vocal parameters of severity, airloss, tension, and pitch, have high intra- and inter-judge reliability. The other vocal parameters indicated no significant reliability coefficients and were seldom marked by the listener-judges. Implications for evaluation of voice/resonance disorders are discussed.
