移動英語學習軟件系統(tǒng)的設計與實現(xiàn)
[Abstract]:With the advent of mobile Internet and social network, people are eager to learn more intelligent and mobile. With the increasing demand for knowledge and the development of modern science and technology, English learning has gradually evolved from a single classroom correspondence to mobile learning at the present stage, which has further promoted the development of information and networking in the English education industry. So that people can learn English anytime, anywhere, really achieve the autonomy of English learning. So that learning more convenient, lifelong, social. In view of the backward learning mode of college English, this paper designs and develops a mobile English learning software system based on speech recognition technology, which is composed of Web server and mobile client. The server uses a stable and reliable Ali cloud server, builds LAMP as the software running environment, realizes user management, English material management and exercise result statistics through the background management module. The mobile side uses iPhone mobile phone with iOS operating system as the hardware platform, and realizes the modules of identity authentication, English course loading, English listening and reading learning and good friend chat and so on. The mobile software uses the HTTP protocol to interact with the background server, obtains the data in JSON format by accessing the data communication interface, and parses the corresponding English audio files and text files. Using components such as tables, views and other components provided by Apple, the data is displayed in a logical way for users to learn, and then the exercise results are uploaded to the iFLYTEK speech recognition engine Center for recognition. The recognition text is compared with the standard text, the corresponding score is obtained and the wrong word red is displayed on the interface to facilitate the user to find the error in the learning process. At the same time, the Sqlite3 database is used for local storage so that the user can learn offline. In addition, the system uses XMPP protocol to realize the function of good friend chat, which is convenient for users to communicate and learn in time. After the design and development of the whole mobile English learning system, the function test and performance test of the server and mobile end are carried out, and it is verified that the mobile English learning software system meets the basic requirements of the subject. And achieve the various functions and performance indicators, for further development to provide a reference.
