PURPOSES:
to investigate the Quality of Life and Voice in addition to the main perceptual-auditory changes and the acoustic measures jitter, shimmer and Glottal Noise Excitation in users of licit and/or illicit psychoactive substances who sought a treatment center for chemical dependency.
METHODS:
cross-sectional study in which participants responded the questionnaires Voice-Related Quality of Life survey and World Health Organization Quality of Life Instrument-Bref. Voice recordings of the vowel /a/ and a count from 1 to 20 were performed. The voice recordings were evaluated by GRBAS-I (G - overall degree of dysphonia, R - roughness, B - breathiness, A - asthenia, S - strain) scale and acoustic analysis by the software VoXmetria.
RESULTS:
29 protocols and voice recordings were assessed, 19 (65.5%) subjects of the sample were male, and the mean age of the sample evaluated was 37.8 years. The scores of both questionnaires indicate no differences between users of licit or illicit drugs. The perceptual analysis through GRBAS-I revealed the prevalence of mild and moderate changes in the items overal degree of dysphonia, roughness, and instability for licit and illicit drug users. Jitter and shimmer were altered for men and women, as was the standard deviation of the fundamental frequency.
CONCLUSION:
changes in quality of life and voice were identified in users of both licit and illicit drugs. Most users showed changes in jitter and shimmer. Illicit drug users had more changes in Glottal Noise Excitation and standard deviation of the fundamental frequency.
