In order to achieve innovative training of English professionals in virtual environments,an open teaching platform in-tegrating English robots and PLC is studied and developed.The platform framework adopts a programmable controller for a Linux+Xe-nomai dual kernel real-time system,and also designs an EtherCAT real-time network card driver to achieve hard real-time multi task synchronization.Compared with CNN,STM-RNN,and pre optimized speech waveform,the amplitude reduction of the optimized speech enhancement algorithm is 18.34%,15.64%,and 11.38%,respectively.The two-stage speech enhancement algorithm can not only preserve good speech structure,but also reduce language distortion and remove residual noise.The open teaching platform for English robots designed by the research institute,which integrates PLC,not only allows for the selection of programmable controllers,but also enables the implementation of motion control program processes through multiple channels.It can also select connected Eng-lish robots through various means,making contributions to the cultivation of talents in the field of English robots and the development of English robot related industries.
