Patent US 4,658,374

A portable electronic language interpreter includes an alphabetical keyboard for entering a particular Japanese word therein using a system of alphabetized Japanese. A retrieval circuit is responsive to the alphabetical keyboard for causing access of a memory containing a plurality of translated English words equivalent to a plurality of Japanese words. A decoder is provided for converting the alphabetized Japanese word into a word in the Japanese "Katakana" language equivalent thereto. A voice synthesizer is provided which generates an audible pronunciation of the input Japanese word. A display is connected to the alphabetical keyboard and the retrieval circuit and decoder for displaying the alphabetized Japanese word, the word represented in the Japanese "Katakana" language, and the translated English word. In a specific form of the present invention, the memory contains at least one pair of translated English words both having a meaning identical to the input Japanese word. In another specific form of the present invention, a phonetic-symbol keyboard may be provided for entering a sequence of phonetic symbols indicating an English word.
