The findings could be especially helpful for stroke patients seeking to improve their speech articulation according to study co-author professor William Katz. These results show that individuals can be taught consonant sounds in part by watching 3D tongue images. But we also are seeking to use visual feedback to get at the underlying nature of apraxia and other related disorders Katz said. The study showed that participants became more accurate in learning new sounds when they were exposed to
