Four normally hearing subjects were trained and tested with all combinations of a highly degraded auditory input, a visual input via lipreading, and a tactile input using a multichannel electrotactile speech processor. When the visual input was added to any combination of other inputs, a significant improvement occurred for every test. Similarly, the auditory input produced a significant improvement for all tests except closed-set vowel recognition. The tactile input produced scores that were significantly greater than chance in isolation, but combined less effectively with the other modalities. The less effective combination might be due to lack of training with the tactile input, or to more fundamental limitations in the processing of multimodal stimuli.
