Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Perceptual-auditory parameters of the voice. The auditory perceptual parameters of the voice were evaluated by three speech therapists specialized in voice using the Visual Analogue Scale (EVA) with a general grade score for sustained emission and another for chained speech;Acoustic parameters of the voice. In the acoustic evaluation, the values of mean fundamental frequency of sustained emission and chained speech, mean chained speech intensity, frequency and intensity disturbance (jitter and shimmer), irregularity, GNE ratio (glottalnoiseexcitation) and HNR noise measure ( harmonic-noise ratio). | — |
Secondary
| Measure | Time frame |
|---|---|
| Self vocal perception, Vocal self-perception was assessed using the Voice Devantage Index - IDV 10 questionnaire.;Electrical activity of supra and infrahyoid muscles Electrical activity was assessed using Surface Electromyography (EMGs).;Superficial temperature of the supra and infrahyoid muscles. The temperature was assessed using Infrared Thermography (TI). | — |
