Speech disorders, or speech impediments as they are also called, are a type of communication disorders where 'normal' speech is disrupted. This can mean stuttering, lisps, vocal dysphonia etc. Someone who is totally unable to speak due to a speech disorder is considered mute.
Classification Classifying speech into normal and disordered is more problematic than it first seems. By a strict classification, only 5% to 10% of the population have a completely normal (with respect to all parameters) and healthy voice, all others suffer from one disorder or another. Dysphonia, that is, incomplete functionality of the vocal folds, is one of the most common and can be observed as, for example, an unusual roughness of the voice. Stuttering is also quite common: about 7% of the population suffer from it at some point in life. Causes There are various causes of speech impediments, such as "hearing loss, neurological disorders, brain injury, mental retardation, drug abuse, physical impairments such as cleft lip or palate, and vocal abuse or misuse." However, in many cases the cause is unknown. Some may be bullied for their disorder, which in many cases, makes matters worse. Treatment Many of these types of disorders can be treated by speech therapy, but others require medical attention by a doctor in phoniatrics. Other treatments include correction of organic conditions and psychotherapy.Many school districts provide the students with speech therapy during school hours. Social effects of speech disorders Suffering from a speech disorder can have negative social effects, especially among young children. Those with a speech disorder can be targets of bullying because of their disorder. The bullying can result in decreased self-esteem. As well, having a speech disorder can cause some sufferers to be shy and have poor public speaking skills. Famous persons with speech impediments | ||||||||
