Resumo
Objetivo: estudar a voz metálica, considerando do ponto de vista fisiológico, os ajustes que ocorrem na velofaringe, faringe e laringe visando fornecer dados adicionais para sua descrição e compreensão.
Métodos: 21 cantores profissionais foram avaliados com exame nasofaringolaringofibroscópico, emitindo a vogal [e] no modo oral e no modo metal. As imagens das seqüências da velofaringe, faringe e laringe foram avaliadas.
Resultados: observou-se, por meio de registro de imagens endoscópicas, relevante incidência de ajustes do trato vocal tais como: abaixamento velar, medialização de paredes faríngeas, elevação laríngea, constrição ariepiglótica e constrição lateral na caracterização fisiológica da voz metálica.
Conclusões: ajustes de velofaringe, faringe e laringe combinam-se na caracterização da voz metálica.

Abstract
Purpose: to study metallic voice by using physiological analysis of adjustments that occur in velopharynx, pharynx and larynx in order to understand its production.
Methods: fiberscopic video pharyngolaryngoscopy was performed on 21 professional singers while speaking vowel /e/ in normal and metallic modes to observe muscular movements and structural changes of the velopharynx, pharynx and larynx.
Results: by means of endoscopic analysis, vocal tract adjustments like velar lowering, pharyngeal wall narrowing, laryngeal raising, aryepiglottic and lateral laryngeal constriction were frequently found in the metallic voice.
Conclusion: adjustments of velopharynx, pharynx, and larynx are combined in characterizing the metallic voice.
