Abstract
Various processes are disclosed for conducting database searches by voice. One such process enables a user to efficiently submit a search query by partially spelling the search query (either on a telephone keypad or via voice utterances) and uttering the full search query. Also disclosed are various processes for generating speech recognition grammars for interpreting utterances of search queries. In one such process, search queries are selected from a search query log for incorporation into a speech recognition grammar. The search query log may include or consist of search queries specified by users without the use of voice.
