The Influence of Auditory Feedback and Vocal Rehabilitation on Prelingual Hearing-Impaired Individuals Post Cochlear Implant.

Objective: To verify changes in the perceptual and acoustic vocal parameters in prelingual hearing-impaired adults with cochlear implants after vocal rehabilitation.

Hypothesis: Auditory feedback restoration alone after cochlear implant is not enough for vocal adjustments. A targeted and specific voice therapy intervention is required.

GRBAS and Cape-V scales: high reliability and consensus when applied at different times.

Objectives: To evaluate whether the overall dysphonia grade, roughness, breathiness, asthenia, and strain (GRBAS) scale, and the Consensus Auditory Perceptual Evaluation-Voice (CAPE-V) scale show the same reliability and consensus when applied to the same vocal sample at different times.

Study Design: Observational cross-sectional study.

Methods: Sixty subjects had their voices recorded according to the tasks proposed in the CAPE-V scale.

Voice analysis of postlingually deaf adults pre- and postcochlear implantation.

Objectives: To ascertain whether cochlear implantation (CI), without specific vocal rehabilitation, is associated with changes in perceptual and acoustic vocal parameters in adults with severe to profound postlingual deafness.

Hypothesis: Merely restoring auditory feedback could allow the individual to make necessary adjustments in vocal pattern.

Study Design: Prospective and longitudinal.

Comparative analysis of the closed quotient for lip and tongue trills in relation to the sustained vowel /ε/.

Various types of trill exercises have been used for a long time as a tool in the treatment and preparation of the voice. Although they are reported to produce vocal benefits in most subjects, their physiology has not yet been studied in depth. The aim of this study was to compare the mean and standard deviation of the closed quotient in exercises of lip and tongue trills with the sustained vowel /ε/ in opera singers.

The relationship between tongue trill performance duration and vocal changes in dysphonic women.

Objective: To assess the relationship between tongue trill performance duration and auditory perception and acoustic changes in dysphonic women.

Study Design: Prospective clinical study, with intrasubject comparison.

Methods: Twenty-seven women who had vocal nodules were in the experimental group (EG) (tongue trills), and 10 were also in the control group (CG) (placebo exercises).
