An apparatus and methods for detecting seat occupancy of a vehicle including a plurality of seats, one or more microphones, and one or more loudspeakers are described. The apparatus in the vehicle includes a digital signal processor coupled to a memory and configured to: determine a first set of transfer functions between the one or more microphones and the one or more loudspeakers based on a first audio signal played from the one or more loudspeakers while passengers are occupying one or more of the plurality of seats. The digital signal processor is configured to apply at least the first set of transfer functions and a second set of transfer functions for the vehicle to a neural network trained on transfer functions for a type of the vehicle to predict a seat occupancy of each of the plurality of seats based on the transfer functions.
