The intelligent English pronunciation training system is an important part of the Android platform, but there is a problem of inaccurate completeness. The previous English pronunciation training system could not solve the problems of accuracy, fluency, and tone of voice in the Android platform, and the completeness was unreasonable. Therefore, this paper proposes a design scheme of intelligent pronunciation training system for accuracy, completeness, fluency and vocal tone analysis. Firstly, the intelligent English pronunciation training system is used to divide the indicators of accuracy, completeness, fluency and vocal tone requirements to reduce the interference factors in accuracy, completeness, fluency and vocal tone. Then, the Android platform forms an accuracy, completeness, fluency, and tone solution for intelligent English pronunciation, and improves accuracy, completeness, fluency, and tone The results were comprehensively analyzed. The results of MATLAB research show that under the condition of a certain completeness standard, this intelligent pronunciation training system is suitable for the Android platform. The accuracy, completeness, fluency, and tone of voice are better than the previous English pronunciation training system.
