Effects of Multisensory Speech Training and Visual Phonics on Speech Production of a Hearing-Impaired Child

A single subject alternating treatments design was used to examine the effects of intensive multisensory speech training with and without the use of Visual Phonics hand cues on the speech production of a profoundly hearing-impaired child. Six target phonemes were trained, three using only multisensory techniques and three using multisensory techniques and Visual Phonics. Daily evaluations of the subject's speech production indicated that all targets showed improvement. The addition of Visual Phonics to multisensory training did not result in speech production gains. All targets were generalized to new words and maintained after the intervention was discontinued.
