Shortcut names corresponding to flagged locations or frequently stated destinations, phrases, or sentences are registered, maintained, used, and deregistered in a speech recognition system. If a flagged location or a frequently stated destination, phrase, or sentence is received by the speech recognition system, the user is prompted to provide a shortcut name corresponding to the frequently stated destination, phrase, or sentence in the form of speech, which is then recognized by speech recognition and registered to a personal profile of the user. The shortcut name is also added to a grammar database of the speech recognition system, so that the speech recognition system may recognize the shortcut name itself. The shortcut name may also be deleted, when speech received from a user contains a shortcut name but the user did not intend the shortcut name to mean the corresponding destination, phrase, or sentence.
