The concept of symmetry applied to the two halves of the human body has long been the object of study by anatomists in relation to discoveries that are directly correlated with health. It can be said that, in the normal man, the general rule is that the two body halves are not perfectly equal, that is, they are asymmetric, it is not easy to establish, in this, also, the limits of normality. Asymmetry may generate a functional dysfunction, which may present greater difficulties in commands to the central nervous system; once one of the injured sides can directly influence the intelligibility of muscle command and vocal domain in Singers. Objective: to analyze the asymmetry in the development of the human voice: the influence on the voice of professional adult singers. Methodology: This is a bibliographical, qualitative review. Data collection was carried out by searching journals indexed in databases: Scielo; Bireme; Lilacs and Medline. Results: 05 researches were selected for the construction of this article, 4 made by speech therapists, 1 made by a singing teacher and speech therapist. There is a general agreement of opinions and opinions regarding the asymmetry in the development of the human voice and the influence on the voice of professional adult singers. The terms symmetry/asymmetry appear related to organs of the body, having great importance for vocal conditioning. The singing voice requires vocal warm-up and cool-down, where the speech therapist works to prevent pathologies caused by the incorrect use of the voice. Speech-language pathologists for singers are responsible for a healthy life, better execution of the singing voice, correct direction of the vocal tract, articulatory, resonant, auditory, warming up, exercising, cooling down and for giving safety to the patient to exercise their profession. Conclusion: In singers, since Voice is a balance of all human body systems working together, we can say that the problematic issue of asymmetry should be seen in a more specific way, which can contribute a lot to improvements in the human voice.
