About

Analyze the effect of SOVTE (Semi-occluded Vocal Tract Exercise), with high resistance tube, on the velopharyngeal mechanism, for speech rehabilitation of twelve patients with cleft palate with vocal alterations, after four weeks. The study was developed in the city of Porto Alegre, southern Brazil. The hypothesis of the study is that after four weeks of exclusive therapy with exercise it will be improvement in the voice of patients with cleft palate.

Full description

The study is an uncompared before-after clinical trial. All patients were submitted to videonasoendoscopy and had their vocal emissions recorded before and after the four weeks of speech therapy. These individuals were submitted to multidimensional evaluation comprised of analysis of images generated by specialized videonasoendoscopy software, analysis of speech emissions by perceptual-auditory evaluation and acoustic analysis, and vocal self-assessment.
