Abstract:
1. A method for coding phonetic information, the method comprising the steps of: identifying phonetic features of a character sequence; representing the identified phonetic features as a bit string, wherein the bit string has a length of 32 bits; replacing at least one group of characters, in the character sequence with a corresponding number of normalized character groups having the same or a similar sound when spoken but a different spelling; covering the beginning portion of the character sequence with a first normalized character group; covering the middle portion of the character sequence with one or more of said normalized character groups; covering the end portion of the character sequence with one of said normalized character groups; coding a first character of the character sequence with five (5) bits; and decreasing a coding precision with a distance from the beginning of the character sequence.
