Abstract:
Normative voice range profiles (VRPs) are calculated for a group of untrained boys and girls between 6 and 11 years based on 35 and 39 recordings, respectively. All individuals had healthy voices. These normative VRPs contain 95% prediction intervals (PI) for both frequency and intensity. They are based on a series of mathematical transformations of the original individual VRPs in order to maintain in the normative VRPs the typical oval VRP shape including the dip between modal and falsetto register. The presented normative VRPs are directly applicable in the clinical practice of otolaryngologists and speech-language pathologists.
