Speech disorders are a type of communication disorders where 'normal' speech is disrupted. This can mean stuttering, lisps, stammering, vocal dysphonia etc. Many of these types of disorders can be treated by speech therapy, but others require medical attention by a doctor in phoniatrics.
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.
Speech disorders, or speechimpediments as they are also called, are a type of communication disorders A communication disorder is a disease or condition that partially or totally prevents human communication.
Speech can be described as the act of producing voice through the use of the vocal cords or other means, such as sign language, to create linguistic acts in the form of language that communicate information from an initiator to a recipient.
In the United States, school-age children with a speech disorder are often placed in special education Special education (also known as special ed, SPED or defectology) refers euphemistically to the teaching of students with a learning disability, a developmental disability or a behavioral problem, or to that of gifted children.
Speech disorders, or speechimpediments as they are also called, are a type of communication disorders where 'normal' speech is disrupted.
There are various causes of speechimpediments, 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 (1).
Those with a speech disorder can be targets of bullying because of their disorder.
