Abstract
A system that allows a user to access a secured area by confirming location of the user near the secured area and receipt of an access word by the system. A user in possession of a mobile device may be detected at the entrance to a secured location. The system can select a question asking for a passcode corresponding to certain access to the secured location. The question can be spoken to a user through a loudspeaker at the secured location. The user's spoken response can be processed by the system, for example using keyword spotting, to determine if the proper access word is included. If it is, the system can grant access to the secured area.
