Speech recognition system for database access through the use of data domain overloading of grammars

A method for voice data entry availability in a voice response system can include receiving speech input specifying data in an audio user interface to a data information system for processing data in a data store. The speech input can be received through an audio user interface to the data information system. Subsequently, speech-to-text conversion of the speech input can be performed using a speech recognition engine with reference to a corresponding speech grammar. In particular, the speech grammar can contain a data set of words relating to the data information system. Notably, the data store can contain a subset of the data set, the subset having words which can be processed by the data information system, the subset not having words which cannot be processed by the data information system. If the specified data is included in the speech grammar and if the specified data is in the data store, the speech data in the speech query can be processed. However, if the specified data is not in the data store, it can be reported that the specified data cannot be processed. Finally, if the specified data is not included in the speech grammar, an Out-Of-Grammar (OOG) condition can be reported. Additionally, the speech data in the speech query is not processed.
