The present invention is a pronunciation correction system for hearing-impaired individuals. It employs an audiometry module to generate hearing impairment data for the hearing-impaired individual. A frequency enhancement module then uses this data to establish a gain model, which is applied to adjust multiple word audios, enabling the hearing-impaired individual to clearly hear the adjusted audios. An assistive learning module plays the adjusted word audios and captures the utterances repeated by the hearing-impaired individual. A speech recognition module performs speech recognition on these utterances, comparing the recognition result with the text labels corresponding to the word audios. The comparison results are sent back to the assistive learning module, which displays visual feedback to display the results. This process assists the hearing-impaired individual in correcting the pronunciation effectively.
