Anarthria is a neurological disorder characterized by the complete inability to articulate spoken words. The word is spelled /ˌænɑrˈθriə/ in IPA phonetic transcription. The first syllable "ana" is pronounced as /ˈænə/ while the second syllable "rth" is pronounced as /ɑrθ/. The third syllable "ri" is pronounced as /ri/ and the last syllable "a" is pronounced as /ə/. The accurate spelling of anarthria can help medical professionals diagnose and treat this disorder effectively.
Anarthria refers to a severe speech disorder characterized by the inability to produce articulate and intelligible speech due to the loss or impairment of the motor control necessary for accurate vocalization. It is considered a pure motor speech disorder, primarily affecting the articulatory muscles and the coordination between the various speech mechanisms involved in speech production, such as the lips, tongue, jaw, and vocal folds.
Individuals with anarthria experience significant difficulty with the precise movements required for clear articulation, resulting in severely distorted or incomprehensible speech. This condition can be caused by various factors, including neurological damage or disorders such as strokes, traumatic brain injuries, degenerative diseases, or certain congenital conditions.
Anarthria is distinct from aphasia, which refers to a language disorder that affects the comprehension and expression of language, not the physical act of speech production. While individuals with anarthria may have intact language abilities in terms of understanding and formulating thoughts, their ability to properly articulate and verbalize these thoughts is hindered.
Treatment for anarthria focuses on improving the coordination and control of the articulatory muscles through various speech therapy techniques, which may involve exercises targeting specific muscle groups, repetition, or the use of alternative communication methods such as augmentative and alternative communication (AAC) devices. The prognosis for individuals with anarthria varies depending on the underlying cause and the individual's response to therapy.

The word "anarthria" has its roots in the Greek language. It is derived from the combination of two Greek words: "an", which means "without" or "not", and "arthros", which means "articulation" or "joint". Therefore, "anarthria" literally means "without articulation" or "lack of joint movement". It is a term used in medicine to describe a condition characterized by the inability to coordinate the muscles necessary for speech.
