Method and system for eliminating redundant voice recognition feedback

#This invention relates generally to voice recognition systems. In particular the invention relates to eliminating redundant voice recognition feedback.

#Voice recognition systems are a common feature in telematics equipped mobile vehicles. A voice recognition system is used to receive spoken commands for operating various systems within the vehicle. Voice recognition systems provide synthesized voice feedback for the commands received by the system. One such command is a phone number to be dialed. For example, a user requests “dial 313-555-1212” and the system responds “dialing 313-555-1212.” If the system is heavily utilized, the voice recognition feedback may be redundant. One such feedback may include phone numbers.

#Redundant voice recognition feedback is often undesirable or annoying for the user. Voice recognition systems do not allow for correction of erroneous requests without canceling and repeating the command. In addition, voice recognition systems cannot provide feature reminders and context sensitive feedback nor allow feedback to be customized to the system user. In another example, if a list of phone numbers is added to an address book, repetition of the phone numbers may be redundant.

#FIG. 1 illustrates one embodiment of a system for eliminating redundant voice recognition feedback, in accordance with the present invention;

#FIG. 2 illustrates a flowchart representative of one embodiment of a method for eliminating redundant voice recognition feedback, in accordance with the present invention;

#FIG. 3 illustrates a first flowchart of the step of determining a voice feedback requirement in accordance with one embodiment of the present invention;

#FIG. 1 illustrates one embodiment of a system for eliminating redundant voice recognition feedback, in accordance with the present invention at 100. The redundant feedback elimination system includes a mobile vehicle communication unit (MVCU) 110, a vehicle communication network 112, one or more embedded modules 139, a command processor such as a telematics unit 120, one or more wireless carrier systems 140, one or more communication networks 142, one or more land networks 144, one or more client, personal, or user computers 150, one or more web-hosting portals 160, and one or more call centers 170. In one embodiment, MVCU 110 is implemented as a mobile vehicle equipped with suitable hardware and software for transmitting and receiving voice and data communications. In one embodiment, a display such as a dialed digital display in a radio unit or in an instrument panel is embedded in MVCU 110. In other embodiments, MVCS 100 includes additional components not relevant to the present discussion. Mobile vehicle communication systems and telematics units are known in the art.

#MVCU 110 is also referred to as a mobile vehicle in the discussion below. In operation, MVCU 110 may be implemented as a motor vehicle, a marine vehicle, or as an aircraft. MVCU 110 may include additional components not relevant to the present discussion.

#Vehicle communication network 112 sends signals to various units of equipment and systems within vehicle 110 to perform various functions such as monitoring the operational state of vehicle systems, collecting and storing data from the vehicle systems, providing instructions, data and programs to various vehicle systems, and calling from telematics unit 120. In facilitating interactions among the various communication and electronic modules, vehicle communication network 112 utilizes interfaces such as controller-area network (CAN), Media Oriented System Transport (MOST), Local Interconnect Network (LIN), Ethernet (10 base T, 100 base T), International Organization for Standardization (ISO) Standard 9141, ISO Standard 11898 for high-speed applications, ISO Standard 11519 for lower speed applications, and Society of Automotive Engineers (SAE) standard J1850 for higher and lower speed applications. In one embodiment, vehicle communication network 112 is a direct connection between connected devices.
