Abstract: Using many speech recognition engines, one can select which one is best at any given iteration of sending a command to a device to be interpreted and carried out. Depending on the context, a different result of many results received from speech recognition engines is chosen. The context is determined based on window history, including rendered webpages represented by URLs previously displayed on the device or windows resulting from executed code on the computing device. In this manner, the operation of the computer is improved as a more accurate result of receiving audio and processing it to text many times is used.
