Abstract
Eleven spondee words produced by six dysarthric and two sensory-deprived speakers were phonetically transcribed in order to determine whether motor and sensory dysfunctions result in distinctive articulatory patterns. In general, the types of articulatory deviations produced by dysarthric speakers were different from those produced by speakers deprived of oral sensation. Stop and fricative error patterns in particular appear to differentiate the two groups of speakers. The results serve to emphasize die unique contribution of information from peripheral oral receptors in the control of ongoing speech.
