Abstract
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.
