Abstract
Less than half of a series of 168 patients with multiple sclerosis presented significant speech deviations. The most frequent speech deviations observed were impaired loudness control and harshness; less frequently occurring deviations were defective articulation, restricted use of vocal variations for emphasis, poor pitch control, hypernasality, inappropriate pitch level, and breathiness. “Scanning speech” was not a prominent characteristic. Speech deviations were not solely attributable to cerebellar involvement. Their incidence was positively related to severity of neurologic involvement, becoming more prominent as additional motor systems were implicated.
