Abstract
In a document retrieving apparatus, an audio input section converts a sound into a character pattern. A language model storing section stores likelihood information. A word choosing section obtains a word selection result based on the likelihood information. A retrieval condition producing section produces retrieval conditions based on the word selection result. A document storing section stores document to be retrieved. And, a document retrieving section retrieves the documents based on the retrieval conditions. An effective document search can be performed regardless of the sentence recognition accuracy without requiring higher cost in collecting the required language data.
