Abstract:     A Chinese speech recognition (SR) method and system for single or un-correlated Chinese character(s). The method uses various types of Character Description Language (CDL) to describe the single or un-correlated Chinese character(s) to be inputted. The SR system uses CDL grammar directed speech recognizer to accept CDLs, which are inputted by voice. On the basis of analysis of CDL parser, the character generator gives a corresponding character. Therefore, recognition of single or un-correlated Chinese character(s) out of context can be made reliably.

First Claim:
Show all 5 claims
What is claimed is:     1. A recognition method for single or un-correlated Chinese character(s) in a Chinese speech recognition system, characterized by the steps of:
  • describing the single or un-correlated Chinese character(s) to be inputted by means of various types of character Description Language wherein the various types of Character Description Language comprise:
    • A) describing a character by an ad hoc word which people usually use;
    • B) describing a character with the help of a related word;
    • C) describing a character taking advantage of Chinese character's structure information;
    • D) describing a character by means of semantics;
    • E) describing a character through stroker; and
    • F) describing single English letter switch Chinese Pinyin, so that a single or un-correlated Chinese character(s) can be described by one of said various types of character Description Language or by combination of them;
  • parsing the inputting various types of Character Description Language; and
  • generating a corresponding character on the basis of parsing analysis.
