Research on Learning Terminal System for English Teaching Practice in Artificial Intelligence

This paper is mainly for the English test terminal research and development. It has realized the functions of question bank, examination, examination statistics and so on. The main feature of the system is that the whole process of using cryptography and digital signature technology, the paper generation process and the content of the examination questions are more fully processed, and also provides a safe and flexible authorized access control mechanism, a complete function of dynamic query and statistical analysis, intelligent paper design. It converts speech recognition and English into Chinese intonation, and designs and develops English translation system at the same time. The deviation between the basic frequency curve of the established tone system and the original sound is only 0.02, and the basic frequency curve is very close. This method can obtain good speech production results, and the generated sounds are diversified and accurate. The CPU usage of this system is 27.8%. Compared with the mobile terminal system and the WEB system, the CPU usage decreased by 19.0%.
