Speech disorder Totally Explained

Everything about Speech Disorder totally explained

Speech disorders or speech impediments, as they're also called, are a type of communication disorders where 'normal' speech is disrupted. This can mean stuttering, lisps, 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 has a completely normal manner of speaking (with respect to all parameters) and healthy voice; all others suffer from one disorder or another.

Stuttering is quite common.
Cluttering, a speech disorder that has similarities to stuttering.
Dysprosody is the rarest neurological speech disorder. It is characterized by alterations in intensity, in the timing of utterance segments, and in rhythm, cadency, and intonation of words. The changes to the duration, the fundamental frequency, and the intensity of tonic and atonic syllables of the sentences spoken, deprive an individual's particular speech of its characteristics. The cause of dysprosody is usually associated with neurological pathologies such as brain vascular accidents, cranioencephalic traumatisms, and brain tumors.

Difficulty in producing specific speech sounds (most often certain consonant, such as /s/ or /r/) may be considered a speech sound disorder, and subdivided into articulation disorders (also called phonetic disorders) and phonemic disorders. Phonetic disorders are characterized by difficulty learning to physically produce sounds, and are popularly referred to as "speech impediments". Phonemic disorders are characterized by difficulty in learning the sound distinctions of a language, so that one sound may be used in place of many. However, it isn't uncommon for a single person to have a mixed speech sound disorder with both phonemic and phonetic components.
There are three different levels of classification when determining the magnitude and type of a speech disorder and the proper treatment or therapy:

Sounds the patient can produce

A: Phonemic- can be produced easily; used meaningfully and contrastively
B: Phonetic- produced only upon request; not used consistently, meaningfully, or contrastively; not used in connected speech

Stimulable sounds

A: Easily stimulable
B: Stimulable after demonstration and probing (for example with a tongue depressor)

Cannot produce the sound

A: Cannot be produced voluntarily
B: No production ever observed

Causes

In many cases the cause is unknown. However, there are various known 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." Child Abuse may also be a cause in some cases.

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.
In the United States, school-age children with a speech disorder are often placed in special education programs. More than 700,000 of the students served in the public schools’ special education programs in the 2000-2001 school year were categorized as having a speech or language impairment. This estimate doesn't include children who have speech/language problems secondary to other conditions such as deafness"

Language disorders

Language disorders are usually considered distinct from speech disorders, even though they're often used synonymously.
Speech disorders refer to problems in producing the sounds of speech or with the quality of voice, where language disorders are usually an impairment of either understanding words or being able to use words and doesn't have to do with speech production
