“…Such a change might result in a real-time processing algorithm, potentially leading to a feasible prosthetic device for rehabilitation of this population [42]. However, as suggested by Clarkson and Bahgat [29], the simplifications imposed on a real-time device could potentially counterbalance the effectiveness of nonreal time algorithms. Therefore, further studies are necessary to determine the effects of simplifications that can be achieved for real-time implementation.…”

In this paper, the details of processing algorithms used in a training program with language learning-impaired children (LLI's) are described. The training program utilized computer games, speech/language training exercises, books-ontape and educational CD-ROM's. Speech tracks in these materials were processed using these algorithms. During a four week training period, recognition of both processed and normal speech in these children continually increased to near age-appropriate levels. We conclude that this form of processed speech is subject to profound perceptual learning effects and exhibits widespread generalization to normal speech. This form of learning and generalization contributes to the rehabilitation of temporal processing deficits and language comprehension in this subject population.
