First Claim
Patent Images
1. A method comprising:
- receiving, in a processor associated with a vehicle, an audio signal;
receiving, in the processor, sound related vehicle information representing one or more sounds, the sound related vehicle information not comprising an audio signal;
selecting a previously generated acoustic model from among a plurality of acoustic models, to decode speech; and
modifying a speech recognition process of the previously generated acoustic model based on the sound related vehicle information, wherein the modifying includes;
determining a pre-trained filter according to filter parameters based on the sound related vehicle information; and
applying the pre-trained filter to the audio signal.
