Flaccid dysarthria is a motor speech disorder resulting from damage to peripheral nervous system (cranial or spinal nerves) or lower motor neuron system. Depending on which nerves are damaged, flaccid dysarthria affects respiration, phonation, resonance, and articulation. It also causes weakness, hypotonia (low-muscle tone), and diminished reflexes.[1][2] Perceptual effects of flaccid dysarthria can include hypernasality, imprecise consonant productions, breathiness of voice, and affected nasal emission.[3]
