20120197637 | SPEECH PROCESSING RESPONSIVE TO A DETERMINED ACTIVE COMMUNICATION ZONE IN A VEHICLE - A system for and method of speech processing for a vehicle. Speech is received from at least one vehicle occupant via a plurality of microphones corresponding to the plurality of zones in the vehicle, wherein the microphones convert the speech into speech signals. At least one active communication zone is determined in which the at least one vehicle occupant corresponding to the active communication zone is speaking Speech processing is modified in response to the determined active communication zone. | 08-02-2012 |
20130211828 | SPEECH PROCESSING RESPONSIVE TO ACTIVE NOISE CONTROL MICROPHONES - Speech processing for a vehicle, including receiving speech from a user via at least one speech microphone that converts the speech into a speech signal, receiving vehicle noise via at least one active noise control microphone that converts the noise into a vehicle noise signal, and processing the speech signal in response to the vehicle noise signal to reduce vehicle noise in the speech signal. | 08-15-2013 |
20130337762 | CALL CENTER BASED ZONED MICROPHONE CONTROL IN A VEHICLE - A method and system for providing call center emergency services to one or more occupants of a vehicle having a plurality of listening zones within a passenger compartment of the vehicle. The method involves detecting a potential emergency condition, sending an emergency notification to a call center, receiving a listening zone control signal identifying at least one of a plurality of listening zones in the vehicle, and supplying audio received from the identified listening zones(s) to the call center via a voice call between the vehicle and call center. | 12-19-2013 |
20130344788 | HVAC SYSTEM ZONE COMPENSATION FOR IMPROVED COMMUNICATION PERFORMANCE - A system, method and apparatus to control climate in multiple zones of a passenger cabin of a vehicle are provided. The system includes a control unit having a receiving unit configured to receive signals from a plurality of microphones associated with each zone of the multiple zones. A determining unit is configured to determine an active microphone from the plurality of microphones based on from which microphone a strongest of the signals was received and to determine an active zone as the zone with which the active microphone is associated. The control unit further includes a fan operating unit configured to control a plurality of fans of the climate control system and to reduce a speed of the at least one fan associated with the active zone in response to the signal received from the active microphone. | 12-26-2013 |
20140074480 | VOICE STAMP-DRIVEN IN-VEHICLE FUNCTIONS - In-vehicle functions are implemented using a plurality of microphones disposed in a vehicle. Each of the microphones is disposed in a portion of the vehicle defined by a zone. The in-vehicle functions are also implemented via a central controller of the vehicle. The central controller includes a computer processor executing logic. The logic receive a voice communication from an individual via one of the microphones, identifies the zone in the vehicle occupied by the individual, identifies the individual by comparing a voice stamp from the voice communication to a database of voice stamps, and implements at least one vehicle electronic component in the zone based on user preferences associated with the voice stamp. | 03-13-2014 |
20160100335 | CONTROLLING VOCODER SELECTION AT A WIRELESS DEVICE - A method of controlling a vocoder selection of a wireless device that uses cellular protocols includes wirelessly receiving an instruction at the wireless device from a wireless carrier system, wherein the instruction includes a vocoder identity that is associated with a particular cellular protocol; identifying a vocoder currently in use at the wireless device; and changing the vocoder currently in use at the wireless device if the identified vocoder is different than the vocoder identity included in the instruction. | 04-07-2016 |
20160119712 | SYSTEM AND METHOD FOR IN CABIN COMMUNICATION - A system and methods are disclosed for improving communication between occupants in a cabin of a vehicle. A source location of a speaking occupant and an output location of a loudspeaker is identified using a microphone array. A beam forming module directs a main beam at the source location and a null beam at the output location. An audible communication from the speaking occupant is received with the microphone array, filtered with a spatial filter based on the main beam and the null beam and broadcast over the loudspeaker. | 04-28-2016 |
20160125865 | SUPPRESSING SUDDEN CABIN NOISE DURING HANDS-FREE AUDIO MICROPHONE USE IN A VEHICLE - A vehicle audio quality system for suppressing sudden vehicle cabin noise is provided, as well as methods of using the system. The system includes: an arrangement of heterogeneous microphones and a noise cancelation module (NCM). The microphone arrangement includes: a first microphone and a plurality of secondary microphones. The NCM includes a controller and a non-transitory computer-readable medium for storing application software executable by the controller to improve the quality of desired cabin audio received by the first microphone, the software performing the steps of: receiving a desired audio input from the first microphone; receiving supplemental audio input via the plurality of secondary microphones that includes a sudden cabin noise input; and applying a suppression procedure to the sudden cabin noise input. | 05-05-2016 |
