Design and implementation of automatic arithmetic generation system based on remote speech recognition

In this paper, an automatic arithmetic generation system which can be remotely controlled by a particular speaker is designed and implemented to improve children´s interest in learning math and facilitate parents to supervise children. The system is composed of the sender subsystem and the receiver subsystem. The sender subsystem is responsible to recognize speech and send the control command, and then the receiver subsystem can receive the command and execute corresponding program. The hardware system is made up of the SPCE061A microchip, keyboard, NRF2401 and LCD SPLC501 etc. The software system mainly achieves the following functions: recognition of speech, the control of NRF2401, random generation of arithmetic test samples, adjustment of different level, and supply of the correct answer. Finally, the system is experimented in some children. The result of experiment shows the system can greatly improve children´s interest in learning math.
