The study aimed to determine whether there is a relationship between acoustic measures and self-evaluation in patients with voice disorders.Study DesignThis is a descriptive, transversal, and observational study.MethodsPatients (257) who answered the Voice Handicap Index protocols (VHI) and the Voice Symptoms Scale (VoiSS) and recorded the vowel /ε/ were included. Standard deviation (SD) measures of the fundamental frequency (F0), jitter, shimmer, and the glottal to noise excitation ratio (GNE) vowel /ε/ were taken.ResultsThere was a weak positive correlation between all scores of VoiSS and the SD of the F0 and jitter. The overall scores, physical limitation, and VoiSS showed weak positive correlations with shimmer. The overall scores, limitation, and emotional VoiSS showed weak negative correlations with the GNE. The VHI did not correlate with any of the acoustic measurements. There was no difference in the mean of the acoustic measures of the SD of F0, jitter, and GNE because of a voice problem detected from the cutoff points of VoiSS. There was no difference in any of the acoustic measurements when patients with and without voice problems were compared from VHI cutoffs.ConclusionsThere is a correlation between the scores of VoiSS and acoustic measurements. Patients with self-reported voice problems in VoiSS present greater deviations in acoustic measures, mainly in jitter. There is no correlation between the VHI scores and the acoustic measures and no difference in the averages of these measures between patients with and without voice problems detected from the VHI cutoffs.
