| Abstract: | The MCU is mainly used as a core of main controlling in the system.The TP3057is used for the code /decode in phonetic.The D6571is used for the conversion of A/D and D/A and phonetic compression.Flash ROM is also used.As a result,the functions of stor-age and play come true.The principle of storage and play in phonetic,the structure of hardware and the design of programming are discussed in this paper. |
