The purpose of the present article is to discuss the physiological and psychological issues relating to psychogenic functional dysphonia through puberphonia of the mutational voice disorder type, by clarifying the aims of speech therapy and the factors that may intervene in the prognosis. The study was conducted based on a systematic search of national and international scientific literature, both current and classical. Based on the aspects covered, it was possible to conclude that therapeutic behavior is founded on techniques that aim to decrease the fundamental voice frequency based on the lowering of the larynx. However, an interdisciplinary approach is required, in view of the fact that the causes of this situation are predominantly emotional.
