Abstract
A vocabulary management system for constraining speech recognition processing associated with text-to-speech and speech-to-text rendering associated with use of a voice application in progress between a user accessing a data source through a voice portal has a vocabulary management server connected to a voice application server and to a telephony server, and an instance of vocabulary management software running on the management server for enabling vocabulary establishment and management for speech recognition software. The system is characterized in that an administrator accessing the vocabulary management server uses the software to create unique vocabulary sets that are specific to selected portions of vocabulary associated with target data sources the vocabulary sets differing in content according to administrator direction.
