Objective: To evaluate psychometric properties of the Voice Symptom Scale (VoiSS) - Chilean Spanish version.
Study Design: Cross-sectional, nonrandomized, prospective study with controls.
Methods: The validation of the Chilean Spanish VoiSS version met the criteria of the Scientific Advisory Committee of the Medical Outcomes Trust: Cultural and linguistic adaptation, by translation into Chilean Spanish and back-translation.
Purpose: To achieve a cross-cultural equivalence of the Chilean version of the V-RQOL protocol, through its cultural and linguistic adaptation.

The existing discrepancies were modified by a consensus committee of five speech therapists and the translated version was entitled Escala de Sintomas Vocales - ESV, with 30 questions and five answers: "Never", "Occasionally", "Sometimes", "Most of the time", "Always".
