Abstract:
A method for providing auditory correction for a hearing-impaired individual, comprising:extracting pitch, voicing, energy and spectrum characteristics of an input speech signal; modifying the extracted pitch characteristic by multiplying a pitch factor times the extracted pitch characteristic; modifying the extracted voicing characteristic by multiplying a voicing factor times the extracted voicing characteristic; modifying the extracted energy characteristic by applying a compression function to the extracted energy characteristic; modifying the extracted spectrum characteristic by applying a homothetical compression function to the extracted spectrum characteristic; and reconstituting a speech signal perceptible to the hearing-impaired individual based on the modified pitch, voicing, energy and spectrum characteristics, wherein the pitch, voicing, energy and spectrum characteristics are modified independently of each other without any reciprocal interaction and are tailored to the hearing-impaired individual.
