20100049516 | METHOD OF USING MICROPHONE CHARACTERISTICS TO OPTIMIZE SPEECH RECOGNITION PERFORMANCE - A system and method for tuning a speech recognition engine to an individual microphone using a database containing acoustical models for a plurality of microphones. Microphone performance characteristics are obtained from a microphone at a speech recognition engine, the database is searched for an acoustical model that matches the characteristics, and the speech recognition engine is then modified based on the matching acoustical model. | 02-25-2010 |
20110051941 | MICROPHONE DIAGNOSTIC METHOD AND SYSTEM FOR ACCOMPLISHING THE SAME - A microphone diagnostic method and system for accomplishing the same are disclosed herein. The method includes generating an analog tone signal and receiving the analog tone signal at a microphone. Via a processor operatively associated with the microphone, the analog tone signal is converted into a digital tone signal and the digital tone signal is compared to a reference digital tone signal having a predetermined amplitude range and a predetermined frequency range associated therewith. The method further includes generating a diagnostic trouble code signal when the digital tone signal falls outside of the predetermined amplitude range, or determining that the microphone is functioning properly when the digital tone signal falls within the predetermined amplitude range. | 03-03-2011 |
20110051972 | ARRANGEMENT FOR MOUNTING A MICROPHONE TO AN INTERIOR SURFACE OF A VEHICLE - A housing sub-assembly for mounting a microphone sub-assembly to a vehicle includes, but is not limited to a main body portion that is adapted to be mounted to an interior surface of the vehicle. The main body portion is configured to connect to the microphone sub-assembly and to support the microphone sub-assembly in a position such that a portion of the microphone sub-assembly protrudes beyond an end of the main body portion when the main body portion is connected to the microphone sub-assembly. | 03-03-2011 |
20110164759 | ARRANGEMENT AND METHOD FOR MOUNTING A MICROPHONE TO AN INTERIOR SURFACE OF A VEHICLE - An arrangement for mounting a microphone to a surface in a passenger compartment of a vehicle includes, but is not limited to, a housing having an opening. The housing is configured to be mounted to the surface. A directional wideband microphone is mounted within the housing and positioned to partition the housing into a first chamber and a second chamber. The directional wideband microphone has an acoustic axis that extends through the first chamber. The housing and the directional wideband microphone cooperate to direct the acoustic axis in a predetermined direction. | 07-07-2011 |
20120008794 | MICROPHONE ASSEMBLY FOR USE WITH AN AFTERMARKET TELEMATICS UNIT - A microphone assembly for use with an aftermarket telematics unit mounted in a passenger compartment of a vehicle is disclosed herein. The aftermarket telematics unit has a chamber having an opening that generally faces towards a rear of the vehicle and the microphone assembly includes, but is not limited to, a directional wideband microphone disposed within the chamber. A preamplifier is internally mounted within the directional wideband microphone. The preamplifier has an electrical lead and is both electrically and structurally attached to the aftermarket telematics unit via the electrical lead. The electrical lead is the sole means of physical attachment between the directional wideband microphone and the preamplifier, on the one hand, and the aftermarket telematics unit on the other hand. | 01-12-2012 |
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 |
20130304475 | SWITCHING BETWEEN ACOUSTIC PARAMETERS IN A CONVERTIBLE VEHICLE - A method of configuring an acoustics system of a convertible vehicle to receive speech from an occupant of the vehicle who is using hand-free technology. The position of the top of the convertible is first determined and based upon whether the top is up or down, an audio reception configuration is selected. The audio reception configuration includes a set of tuning parameters and a microphone arrangement. The acoustics system is then configured based upon the determination of whether the top is up or down. | 11-14-2013 |
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 |
