This article presents an overview of information on the development of voice, based on a detailed analysis of the literature. The data demonstrate voice abnormalities in individuals with hearing impairment as compared to individuals with normal hearing. Many researchers believe that the main factor leading to voice abnormalities among hearing-impaired individuals is incorrect auditory feedback resulting from higher hearing thresholds. This lack of feedback leads to abnormal encoding of neuronal patterns in cortical regions of the brain, which results in a disrupted control of internal and external laryngeal muscles.
