汉语拼音的短韵母编码与汉字输入

Shortened Finals of Chinese Syllables and Application for Hanzi Input

《汉语拼音方案》在中文信息处理中具有重要地位，拼音输入法更是电脑汉字输入的大众化方法。由于韵母采用1～4个字母，显得长短不齐。本文提出短韵母编码方案，除原来单字母韵母外，其他韵母用{aoeiuv}中的两个字母来表示，使得拼音编码变短。由于韵母采用的字母与声母采用的20个字母不同，在键盘输入汉字时可以采用“声韵声”方式输入词组。此方案可用于字母键盘，在数字键盘更有优势。声调的4个键与短韵母编码的6个键互不相同，拼音串输入时容易切分各字拼音，即使省略了韵母。每对模糊音设有3个数字键盘编码，以方便部分字音需要模糊的用户。

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.
