ABSTRACT:
A recognition method for alpha-numeric strings in a Chinese speech recognition system, uses a special coding scheme to map each of 36 alpha-numeric symbols into an easily remembered Chinese idiom or word consisting of a multiple of Chinese characters. When representing a numeral, each idiom/word starts with the Chinese character for that numeral. When representing an English alphabet letter, each idiom/word will have a first character which starts with that English alphabet letter in its Pinyin form. If it is necessary to include some control words, idiom/words similar in semantics can be used. The method resolves the problem of unreliable recognition when a string of random alpha-numeric symbols or some control words are inputted by voice to a Chinese speech recognition system.
