Abstract：The scheme of Chinese phonetic alphabet plays an important role in Chinese information processing. Hanzi input by Pinyin is one of popular Methods in China.. The number of characters in the final of Chinese syllable is from 1 to 4. A compressed scheme to shorten the finals is proposed. The finals with 2 to 4 characters originally is coded by only 2 characters in the set of {a,o,e,i,u,v} in order to make them short. For the characters in the finals are different from the 20 characters in the initials of Chinese syllable. Hanzi input with keyboard for Chinese phrase can be done by the combination of “initial, final, initial”. This scheme can be used in alphabet keyboard and even better in numeric keypad. 4 keys for tones of pinyin are different with the 6 keys for the finals, so the boundary of each syllable is clear even the finals are omitted. Each pair of fuzzy initials or finals has 3 codes in numeric keypad, in order to help these users who need the fuzzy code for partial Chinese characters.
