Design and Research of the Spoken English Test System Based on Node.js

摘要

Online spoken English test system has become one of the most important methods of examination in the Internet era. Compared with the traditional software developed by C++/C#, this paper mainly uses Nw.js development framework based on Node.js platform, which reduces the cost and difficulty of system development and enhances software compatibility and flexibility [1]. The server based on Node.js gets examination papers from the cloud and sends them to the client while the client records audio and sends the files coded with Lame back to the server, between which we use WebSocket for TCP/IP communication. The test result shows that the system can provide real-time online spoken English test for up to 5000 users.
