Abstract

A modular speech recognition system (201) includes a bulk memory (230) that stores a plurality of specialized vocabulary databases (231), a front end processor (305) that generates a first set of feature vectors based on an analysis of a first set of sampled speech data received during a call, a local memory (370) that stores a specialized vocabulary database (371); and a recognition processor (355) that accepts the first set of feature vectors and generates a recognition result based on the first set of feature vectors and specialized vocabulary database. The specialized vocabulary database (371) is a copy of one of the plurality of specialized vocabulary databases (231) stored in the bulk memory (230). The specialized vocabulary database (231) is selected from the plurality of specialized vocabulary databases (371) in response to information associated with the call.
