Purpose: to characterize and reflect on the process of cultural equivalence and/or validation of vocal self-assessment instruments translated and adapted for the Brazilian Portuguese, used in clinical practice and scientific research. Research strategies: The articles were searched in the following databases: SciELO, LILACS, PubMed and "The Cochrane Library". Selection critéria: The studies were selected regarding the presence of the descriptors cited in their title, abstract or descriptors; validation articles of self-assessment instrument in voice or with the objective of performing cultural equivalence; being directed to the Brazilian population; original studies with a sample of human beings; regardless of the age of the life cycle type of dysphonia or vocal symptoms. Results: Nine articles were found that addressed the objectives of this review. Voice quality of life and vocal handicap were the most addressed constructs. Most validations occurred in the Southeast region of Brazil. Most of the scores of the instruments are calculated by simple sum of the answers given by the participants in the component items; cut-off points are not always displayed. The domains of the instruments, as well as the items that compose them, were maintained as presented in the instrument in its original language. The most common statistic for instrument analysis was crombach's Alpha coefficient. Conclusion: The constructs most covered in the selected articles were voice quality of life and vocal handicap index. The instruments were considered valid and sensitive for vocal self-assessment, although in some are not considered all the steps proposed internationally, ideal for validation of health instruments during the process.
