1. A system for adjusting vehicle components based on audible commands received within a vehicle, the system comprising:
a plurality of adjustable vehicle components;
an audio device configured to receive an audible command from an occupant within the vehicle and generate corresponding command data; and
a controller programmed to generate a first confidence score and a second confidence score based on the command data and determine whether the second confidence score meets a second threshold after determining whether the first confidence score meets a first threshold,
the controller further programmed to (i) cause a first response to be output from the audio device after determining that the first confidence score does not meet the first threshold, (ii) cause a second response to be output from the audio device after determining that the second confidence score does not meet the second threshold, the second response different from the first response, and (iii) cause an adjustment of at least one adjustable vehicle component of the plurality of adjustable vehicle components after considering the first threshold and then the second threshold and determining that the first confidence score does not meet the first threshold but the second confidence score meets the second threshold and one or more word matching a function from a narrowed list of functions corresponds to current context data from one or more vehicle sensor related to the function.
