US Patent 11404075 Vehicle voice user interface

Techniques for confirming an operator of a vehicle is drowsy are described. A vehicle computing system sends data (e.g., raw sensor data and/or alert data corresponding to an indication that a driver is impaired determined based on the raw sensor data) to a remote server(s). The remote server(s) confirms the driver is impaired based on the raw sensor data and/or other contextual data. The remote server(s) then receives output data from a speechlet and causes the vehicle computing system to present output audio corresponding to output data.
