Method and device for enhancing the recognition of speech among speech-impaired individuals
First Claim
1. A method of teaching temporally impaired individuals to discriminate between the stimuli of at least two rapidly changing frequencies of consonant sounds, the method comprising the steps of:
- a) separating the at least two differing sound stimuli to provide an interstimulus interval of at least 100 milliseconds;
b) prolonging the consonant sound in each of the stimuli by a factor of at least thirty percent;
c) repeating the at least two differing stimuli in random order until the temporally impaired individual is able to distinguish the order of each stimulus;
d) decreasing the interstimulus interval by at least a one percent factor;
e) repeating step c) with a decreased interstimulus interval until the temporally impaired individual is able to distinguish the order of each stimulus; and
,f) repeating steps c) through e).

Abstract
A method and a system is disclosed that provide means to enable individuals with speech, language and reading based communication disabilities, due to a temporal processing problem, to improve their temporal processing abilities as well as their communication abilities. The method and system include provisions to elongate portions of phonemes that have brief and/or rapidly changing acoustic spectra, such as occur in the stop consonants b and d in the phonemes /ba/ and /da/, as well as reduce the duration of the steady state portion of the syllable. In addition, some emphasis is added to the rapidly changing segments of these phonemes. Additionally, the disclosure includes method for and computer software to modify fluent speech to make the modified speech better recognizable by communicatively impaired individuals. Finally, the disclosure includes method for and computer software to train temporal processing abilities, specifically speed and precision of temporal integration, sequencing and serial memory.
