This paper proposed a speech-controlled real-time remote vehicle On-Board Diagnostic (OBD) system for telematics applications. The proposed system contains three main parts. They are OBD embedded global position system (GPS-OBD) module, speech-controlled interface, and vehicle surveillance server. In addition to the real-time vehicle time-location information including date, time, longitude, and latitude obtained from GPS receiver, the GPS-OBD module can also record the real-time vehicle operation information including vehicle speed, engine rpm, coolant temperature, battery voltage, fault code number, and others from OBD system. These real-time vehicle data, i.e., vehicle time-location and operation information, will be uploaded to the vehicle surveillance server via 3.5G network. Meanwhile, the GPS-OBD module can be operated through the speech-controlled interface.
