Abstract

Purpose: To assess data collection variability in the Voice Range Profile (VRP) across clinicians and researchers, a systematic review was conducted to evaluate the extent of variability of specific data collection points that affect the determination of frequency range and sound level and determine next steps in standardization of a VRP protocol. Method: A systematic review was conducted using the Preferred Reporting Items for Systematic Review and Meta-Analysis checklist (PRISMA). Full text journal articles were identified through PubMed, Web of Science, Psych Info, ProQuest Dissertations and Theses Global, Google Scholar and hand searching of journals. Results: A total of 1134 articles were retrieved from the search; of these 463 were duplicates. Titles and abstracts of 671 articles were screened, with 203 selected for full-text review. Fifty- four articles were considered eligible for inclusion. The information extracted from these articles revealed the methodology used to derive the VRP was extremely variable across the data points selected. Additionally, there were 8 common acoustic measures used for statistical analysis described in included studies that were added as a data point. Conclusions: The data collection methods for the VRP varied considerably. Standardization of procedures were recommended for clinicians and researchers.
