Possibilities of Compensating for Defects in Speech Perception and Production

In order to investigate possibilities of compensating for defects in both speech perception and production processes, functions involved in possible modes of linguistic information processing for speech and letters are modeled, taking into account the structural parallel between steps involved in the processing of speech and letters. Interconnections between perception and production processes, and between phonological and orthographic components are also provided. First, using this model, various aspects of compensation found in normal processes are discussed, using examples of speech production such as lip spreading or rounding for vowels, and lingual contact with the palate for vowels and consonants. Then, the possibility of the use of substitutive sensation is overviewed, considering enhancement of ordinary functions, perception of speech through other sensations, speech supplements through other sensations, speech-to-letter conversion, and perception of letters for speech. The use of substitutive organs is overviewed, considering substitutive aids for ordinary organs, production through other organs, and production of letters for speech. Finally, to promote the combined use of auditory, visual and tactile channels of sensation in speech perception, complementary effects between the sensation channels are discussed.
