Abstract:With the development of multimedia information processing technology, Audio processing technology has been widely applied. Speech technology is using digital signal processing technology, the audio signal of a subject, in a multidisciplinary developed on the basis prehensive technical. Speech technology involve digital signal processing, pattern recognition, voice science, linguistics and artificial intelligence, and other disciplines. This paper introduces a Bus reporter system.. In the present time, public buses are still the best choice when people travel, though the private cars are more and more, because public buses are convenient, speedy, and the tickets are cheap. The Process to achieve its function is: Take the MCU as the nucleus module, the determinant keyboard scanning as the control importation and realize the display driver and voice module station reported. The system reliability, availability, portability strong, low-cost, easy to operate, is suitable for the public transportation use.
Keywords:Single-chip puter control,Voice chip,Chinese character LCD display,Speech processing
