Method and apparatus for transducer-based text normalization and inverse text normalization
First Claim
Patent Images
1. 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.

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.
