1. A method of improving recognizability of a voice command comprising:
capturing a voice command of a vehicle occupant through a microphone, the voice command including background noise associated with vehicle operation; using information on a vehicle system that relates to sounds in the vehicle to obtain a vehicle parameter describing a state of the vehicle system; using a vehicular dialogue system to: construct a digital interference profile including noise type and noise level in accordance with the vehicle parameter describing the state of the vehicle system; select a pre-trained acoustic model based on the interference profile; apply the pre-trained acoustic model to the voice command so as to generate a voice command modification having enhanced recognizability, the pre-trained acoustic model generated from supervised learning of records of the noise type and the noise level; synthesize an audio prompt requesting clarification of the voice command modification, the audio prompt having a modified syllable duration and a modified prompt spectrum in accordance with the interference profile; andinitiate a vehicular action in accordance with the voice command modification.
