Abstract
A dictation system (100) performs a method of dictating speech which automatically activates (502) and deactivates (306, 408, 510) auxiliary topic libraries based on the input speech. After receiving (206) input speech, the method searches (208, 214) a general library and topic libraries that are currently active, if any. The method also searches (220, 226) all or portions of inactive topic libraries. If the spoken word is recognized in a particular inactive topic library, the method automatically activates (502) that topic library. In a preferred embodiment, the method maintains an adjustable “score” for each active topic library. An active library's score is increased (402) each time a word is recognized in the library, and decreased (302, 404, 506) when a word is recognized in another library. If the score falls below a certain threshold, the active topic library is automatically deactivated (306, 408, 510).
