The purpose of this study was to compare the speechreading abilities of elementary school-age children with mild to severe articulation disorders with those of children with normal articulation. Speechreading ability, as determined by a speechreading test, indicates how well a person recognizes the visual cues of speech. Speech sounds that have similar visual characteristics have been defined as visemes by Jackson in 1988 and can be categorized into distinct groups based on their place of articulation. A relationship between recognition of these visemes and correct articulation was first proposed by Woodward and Barber in 1960. Dodd, in 1983, noted that speechread information shows a child how to produce a sound, while aural input simply offers a target at which to aim.
