HYBRID ORIENTAL CHARACTER RECOGNITION TECHNOLOGY USING KEY PAD AND VOICE IN ADVERSE ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for inputting an oriental language such as Chinese with very high precision for a small-sized electronic device such as a PDA, a mobile telephone set, an electronic dictionary, and an electronic wristwatch having several key pads and/or a memory with small capacity. SOLUTION: To further solve the vagueness resulting from the vocalization of each multisyllabic Chinese word in isolated intonation syllables having vowels and consonants separated through automatic syllable recognition and the acoustic realization of Pinyin pronunciation (minor word unit) as, for example, a consonant in adverse environment, the depression of one of specially designed key pads, for example, key pressing operation including the 1st phoneme (consonant or vowel) of a syllable is done. If vagueness remains, the 2nd or 3rd Pinyin pronunciation of the syllable needs to be pressed. The key pads are designed on a data-initiative basis so that the ratio of similarity of phonemes of the respective key pads is minimized and the ratio of similarity of Pinyin pronunciation between keys is maximized.
