VEHICLE COMMUNICATION SYSTEM
First Claim
Patent Images
1. A vehicle communication system comprising:
- a plurality of microphones adapted to detect speech signals of different vehicle passengers, each microphone producing an audio signal component;
a mixer combining the audio signal components of the different microphones to produce a resulting speech output signal; and
a weighting unit determining the weighting of the audio signal components for the resulting speech output signal, where the weighting unit determines the weighting of the signal components based upon non-acoustical information about the presence of a vehicle passenger.

8. A vehicle communication system comprising:
-
a plurality of microphones adapted to detect speech signals of different vehicle passengers, each microphone producing an audio signal component;
a mixer combining the audio signal components of the different microphones to produce a resulting speech output signal;
a seat occupancy detecting unit detecting the presence of non-occupied vehicle seats; and
a weighting unit determining the weighting of the audio signal components for the resulting speech output signal, where the weighting unit sets the weighting of audio signal components of non-occupied seats to zero.

9. A method for controlling a speech output of a vehicle communication system, the method comprising:
-
detecting speech signals of at least one vehicle passenger using a plurality of microphones, each microphone producing a speech signal component;
weighting the speech signal components detected by the different microphones; and
combining the weighted speech signal components to a resulting speech output signal, where the weighting of the different speech signal components is based upon non-acoustical information about the presence of vehicle passengers. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
