System and method for acoustic transformation

Abstract

An acoustic transformation system and method. A specific embodiment is the transformation of acoustic speech signals produced by speakers with speech disabilities in order to make those utterances more intelligible to typical listeners. These modifications include the correction of tempo or rhythm, the adjustment of formant frequencies in sonorants, the removal or adjustment of aberrant voicing, the deletion of phoneme insertion errors, and the replacement of erroneously dropped phonemes. These methods may also be applied to general correction of musical or acoustic sequences.

Description

[0001] cross reference [0002] This application claims priority to US Patent Application Serial No. 61 / 511,275, filed July 25, 2011, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates generally to acoustic transformations, and more particularly, the present invention relates to acoustic transformations for improving the intelligibility of speakers or voices. Background technique [0004] There are currently some examples of sounds being produced inaccurately, with the result that the sound heard is not the sound that was intended. Speakers with dysarthria often produce speech sounds inaccurately. [0005] Dysarthria is a group of neurological movement disorders that impair the physical production of speech. These lesions reduce normal control of the primary vocal organs but do not affect the normal understanding or production of meaningful, grammatically correct speech. For example, damage to the recu...
