Abstract
An apparatus and method for training of auditory and graphical discrimination in humans is provided. The method and apparatus provides a number of stimulus sets, each stimulus set having a target phoneme, and associated grapheme, and a number of distractor phonemes, and associated graphemes. Upon initiation of a trial, a target phoneme is presented to a subject. A stimulus stream is then prepared that consists of a random sequence of distractor phonemes. Located within the sequence of distractor phonemes is the target phoneme. The stimulus sequence is presented to the subject for identification of the target phoneme within the sequence. Speech processing is used to provide multiple levels of emphasis for enhancing a subject's ability to discriminate between similarly sounding phonemes. The processing is applied to the presentation of the target phoneme and the stimulus stream. As a subject correctly identifies target phonemes within stimulus streams, across all provided stimulus sets, the amount of processing applied to the phonemes is reduced, ultimately to the level of normal speech.
