Abstract
The disclosure generally pertains to systems and methods for identifying a location of an occupant in a vehicle. In an example method, a processor deconvolves a vocal utterance by an occupant of a vehicle and also determines an angle of arrival of the vocal utterance. The location of the occupant in the vehicle is then identified by the processor based on evaluating the deconvolved vocal utterance and the angle of arrival of the vocal utterance. Deconvolving the vocal utterance can involve applying a cabin impulse response to the vocal utterance for eliminating undesirable effects that may be imposed upon the vocal utterance by acoustic characteristics of the cabin of the vehicle (echo, sound reflections, sound damping, reverberation etc.). In some applications, the processor may refer to a lookup table to estimate a location of the occupant in the vehicle.
