US Patent 11273778 Vehicle voice user interface

Techniques for engaging a drowsy or otherwise impaired driver of a vehicle in a VUI dialog are described. A vehicle computing system sends data (e.g., raw sensor data and/or an indication that a driver is impaired determined based on the raw sensor data) to a remote server(s). The remote server(s) may separately determine whether the driver is impaired based on the raw sensor data and/or other contextual data. The remote server(s) selects a speechlet to provide output data based on the sensor data, contextual data, and or a level at which the driver is impaired. The remote server(s) then causes the vehicle computing system to present output audio corresponding to output data provided by the speechlet.
