A data communications bus 14 runs through the vehicle and interconnects a variety of components within the vehicle. Many standards exist for specifying bus operations such as, for example, SAE J 1850, Controller Area Network (CAN), and the like. Various manufacturers provide bus interfaces that handle low level signaling, handshaking, protocol implementation, and other bus communication operations.
Appliance 12 is connected to bus 14 to be in communication with other vehicle components connected to the bus. In this embodiment of the present invention, other vehicle components connected to bus 14 include vehicle speakers 16, clock 18, thermometer 20, compass 22, and speedometer 24. Speakers 16 are operable to output audible sounds including music from a radio of the vehicle. Clock 18 monitors the current time. Thermometer 20 monitors the temperature outside of the vehicle. Compass 22 monitors the current vehicle direction. Speedometer 24 monitors the current vehicle speed.
Bus 14 transfers information monitored by clock 18, thermometer 20, compass 22, and/or speedometer 24 to appliance 12 for the appliance to audibly output through speakers 16 for the user to hear in response to the user speaking a request for such information while the appliance is in the vehicle status information mode. As such, the user hears the monitored information requested by the user instead of visually seeing such information on a display. A brief example is as follows. The user requests information regarding the current direction of the vehicle by speaking the a phrase containing “compass”, “vehicle direction”, etc., while appliance 12 is in the vehicle status information mode. In turn, appliance 12 obtains the current vehicle direction (e.g., north) from compass 22 via bus 14 and then audibly announces the word “North” through speakers 16 via bus 14 for the user to hear.
Appliance 12 includes a processor 26. Processor 26 controls and enables the overall operation of telephone system 10. Processor 26 places appliance 12 in the phone mode upon: a user actuating a phone button 28 of the appliance; detection of an incoming call to the user; a user speaking certain phone commands into a voice-recognition (VR) microphone 30 of the appliance. With respect to the last option, appliance 12 includes a voice recognition unit (VRU) 32. VRU 32 in conjunction with other elements of appliance 12 enables a user to speak phone commands for answering and making cell phone calls and re-dialing numbers via a cell phone instead of manually handling the cell phone to do so. VRU 32 is connected to VR microphone 30 to receive the phone commands spoken by the user. VRU 32 converts the spoken phone commands into corresponding electrical signals for use by processor 26. For example, VRU 32 translates the phone command “dial” into a corresponding signal; translates numeric characters spoken by the user into corresponding signals; etc.
Regarding the operation of appliance 12 in the phone mode, the appliance includes a Bluetooth enabled communications module 36. Communications module 36 is operable for wirelessly communicating with Bluetooth enabled devices such as a Bluetooth enabled cell phone 38 in the vehicle. Communications module 36 wirelessly communicates with cell phone 38 during a call over a telecommunications network between a user using the cell phone and an external party while appliance 12 is in the phone mode. Operation of appliance 12 during the call is as follows. The user audibly talks out loud in the vehicle during the call just like the user would talk into cell phone 38 during the call. A phone microphone 40 of appliance 12 converts the audible sounds of the user into corresponding electrical voice signals. Phone microphone 40 is connected to communications module 36 via processor 26 or is directly connected to the communications module. In any event, communications module 36 receives the voice signals from the user via phone microphone 40 and wirelessly communicates the voice signals to cell phone 38 for transmission over the telecommunications network for receipt by the external party. Likewise, during the call, communications module 36 wirelessly receives the voice signals from the external party from cell phone 38 and outputs the voice signals of the external party through speakers 16 for the user to hear.
Processor 26 places appliance 12 in the vehicle status information mode upon a user manually actuating a voice-recognition (VR) button 34 of appliance 12. Processor 26 places appliance 12 in the vehicle status information mode upon a user speaking certain appliance commands into VR microphone 30 of the appliance. For example, processor 26 places appliance 12 in the vehicle status information mode upon the user speaking the command “vehicle status information mode”.
Regarding the operation of appliance 12 in the vehicle status information mode, the appliance includes a voice synthesizer 42 in addition to VRU 32. Voice synthesizer 42 generates computerized voice signals of information monitored by clock 18, thermometer 20, compass 22, and speedometer 24 for speakers 16 to output for the user to hear. As such, the user hears such information instead of visually seeing this information on a display.

Initially, a user speaks a request for information monitored by a vehicle component into VR microphone 30 as shown in block 52. For example, a spoken request of the user may be a question such as “What is the ______?” where “______” is any one of “vehicle direction”; “temperature”; “time”; “vehicle speed”; etc. VRU 32 translates the spoken request into a corresponding information request signal for use by processor 26 as shown in block 54. Processor 26 uses the information request signal to determine the vehicle component (i.e., compass 22, thermometer 20, clock 18, or speedometer 24) corresponding to the request as shown in block 56. That is, processor 26 uses the information request signal to determine which vehicle component is responsible for the requested information. Processor 26 then communicates with the determined vehicle component via bus 14 to obtain the requested information as shown in block 58. Processor 26 then provides a signal indicative of the obtained information to voice synthesizer 42 as shown in block 60. Voice synthesizer 42 converts the signal indicative of the information into a corresponding computerized voice signal and transfers the computerized voice signal to speakers 16 via bus 14 as shown in block 62. Speakers 16 output the computerized voice signal of the requested information for the user to hear as shown in block 64.

Appliance 112 includes a processor 114. Processor 114 generates the garage door control signals when appliance 112 is in the garage door control mode.
Processor 114 is connected to vehicle bus 14 to obtain vehicle component information from vehicle components (e.g., clock 18, thermometer 20, compass 22, speedometer 24, etc.) when appliance 112 is in the vehicle status information mode. Appliance 112 includes its own speaker 116 and microphone 118. Processor 114 generates a computerized voice signal indicative of the obtained vehicle component information and provides the signal to speaker 116 for the speaker to audibly announce to a user. Processor 114 obtains the vehicle component information in response to microphone 118 receiving a spoken request by a user for such information. To this end, processor 114 includes a VRU for translating the spoken request to determine the vehicle component information desired by the user. Appliance 112 further includes a button or the like to enable a user to submit a request for vehicle component information manually by pressing the button instead speaking a request for such information into microphone 118. As indicated, processor 112 may automatically obtain information from the vehicle components via vehicle bus 14 and announce such information through speaker 116 for a user to hear without the user requesting such information. This may occur during certain time periods (e.g., during initial starting/stopping of the vehicle), at special events (e.g., when certain vehicle component thresholds are reached), periodically every hour, etc. Further, appliance 112 may include its own voice synthesizer and/or VRU in the same manner as telephone system 10 for use in obtaining vehicle component information requests from users and/or audibly announcing obtained vehicle component information.
