Pronunciation correction system for hearing-impaired individuals

A pronunciation correction system for hearing-impaired individuals, comprising:

• an audiometry module, configured to generate a hearing impairment data of a hearing-impaired individual;
• a frequency enhancement module, configured to establish a gain model based on a hearing threshold differences between the hearing impairment data and a hearing data of a normal individual, and the frequency enhancement module configured to adjust word audios by the gain model and generate adjusted audios, when the adjusted audios heard by the hearing-impaired individual, the frequency enhancement module configured to provide an auditory perception experience equivalent to that of a normal individual;
• an assistive learning module, configured to play the adjusted audios and capture repeated pronunciations of words spoken by the hearing-impaired individual who hears the adjusted audios;
• a speech recognition module, configured to perform a speech recognition on the repeated pronunciations of the words spoken by the hearing-impaired individual, and to compare recognition results with text labels corresponding to the word audios to generate a comparison result, wherein the comparison result is sent back to the assistive learning module, which provides visual feedback to display the comparison result.
