Abstract
Systems, methods, and devices for location-based context driven speech recognition are disclosed. A mobile or stationary computing device can include position locating functionality for determining the particular physical location of the computing device. Once the physical location of the computing device determined, a context related to that particular physical location. The context related to the particular physical location can include information regarding objects or experiences a user might encounter while in that particular physical location. The context can then be used to determine delimited or constrained speech recognition vocabulary subset based on the range of experiences a user might encounter within a particular context. The speech recognition vocabulary subset can then be referenced or used by a speech recognizer to increase the speed, accuracy, and effectiveness in receiving, recognizing, and acting in response to voice commands received from the user while in that particular physical location.
