Abstract
A method and apparatus are provided that perform text normalization and inverse text normalization using a single grammar. During text normalization, a finite state transducer identifies a second string of symbols from a first string of symbols it receives. During inverse text normalization, the context free transducer identifies the first string of symbols after receiving the second string of symbols.
Claims22
A method for performing text normalization and inverse text normalization, the method comprising:
- receiving a first string of symbols;
- using a grammar to identify a second string of symbols from the first string of symbols;
- providing the second string of symbols as the text normalization of the first string of symbols;
- receiving the second string of symbols;
- using the grammar to identify the first string of symbols from the second string of symbols;
- and
- providing the first string of symbols as the inverse text normalization of the second string of symbols.
A computer-readable medium having computer-executable instructions for performing steps comprising:
- performing text normalization using a context free transducer and a grammar;
- performing inverse text normalization using a context free transducer and the grammar.
A computer-readable medium having computer-executable instructions for performing steps comprising:
- providing an input text and a context free transducer network to a context free transducer that is capable of performing text normalization or inverse text normalization using the context free transducer network;
- and
- instructing the context free transducer to perform one of text normalization or inverse text normalization.
