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