Method of processing a voice segment and hearing aid

摘要

A method of processing a voice segment (21, 21a, 21b, 21c) includes checking whether a voice segment (21, 21a, 21b, 21c) is a vowel segment. If the voice segment (21, 21a, 21b, 21c) is not a vowel segment, then the process checks whether the voice segment (21, 21a, 21b, 21c) is a high frequency consonant or a low frequency consonant. If the voice segment (21, 21a, 21b, 21c) is a high frequency consonant, then the voice segment (21, 21a, 21b, 21c) will be processed to lower its frequency.
