Abstract
Various processes are disclosed for conducting database searches by telephone. A user is initially prompted to utter N characters of a search query, and/or to enter these characters on a telephone keypad. Based on the user's entry, a speech recognition grammar is either selected or is generated dynamically for processing the user's utterance of the complete search query. In one embodiment, the speech recognition grammar is selected based on a sequence of N telephone keys selected by the user, without requiring the user to uniquely specify the N characters to which these keys correspond. In another embodiment, the speech recognition grammar is selected based solely on utterances of the N characters by the user such that the correct grammar is selected even if an utterance of one character is misidentified as an utterance of a similar sounding character. Also disclosed are methods for generating speech recognition grammars from query logs.
