Abstract
A method of determining contexts for a vehicle, each context corresponding to one or more events associated with the vehicle, for example that the radio is on and a window is open. The method comprises detecting sound activities in an audio signal captured in the vehicle, and assigning context to the vehicle based on the detected sound activities. Non-audio data such as the operational status of a vehicle system or device is used to help assign contexts.
