Applied Research, The Cloud Model In The Teaching System Of Digital Voice

With the rapid development and improvement of the computer's multimedia technology and the network technology, Digital voice-teaching has become an inevitable trend. The character of Digital voice-teaching system is high efficiency, stability and share, the application of the Digital voice-teaching System has taken fundamental changes to the voice-teaching System through its content, means and even the concepts. The advantages of Embedded systems is small size, low power consumption, high reliability, good tailoring, and so on, which made Embedded System become another new dominate behind the PC. In such premise, this thesis introduces the research and design of the Digital voice-teaching System based on Embedded System. The system adds a new function of the evaluation of students' study, using a new method of student evaluation of learning results——the model based on cloud theory to evaluate students' learning results. The model will help teachers and students understanding of the dynamic study, embodying the spirit of people-oriented, improving the teaching effectiveness and studying quality.To meet the need of the Digital voice-teaching system, we construct architecture of the system based on the embedded system in this thesis. Embedded Digital voice-teaching system based on the introduction of the concept of cloud model. In order to further study the using of cloud model at the personalized teaching applications.This thesis firstly, introduces the development trends and status quo of the voice classroom, secondly researches the key technologies of cloud model, thirdly the system's various functional modules are designed after the overall analysis on the intelligent voice-teaching system, and put cloud model applied to the evaluation of students' study. Finally, the thesis presents the Digital voice -teaching system based on the cloud model form teacher terminal and student terminal respectively.
