摘要 数字语言学习系统随着计算机、网络、多媒体的发展越来越普及,为了实现其很好的教学效果,需要语音的传递实时性强,能实现语音的多点通信和分组通信。随着DSP技术的发展,将DSP技术运用到该数字语言学习系统,实现语音信息数字化和数字通信网络化,采取DMA读取硬盘的方式,使得该系统性能好,达到了实现全数字语言教学的目的。 Digital language learning system is becoming more and more popular with the development of computers,networks and multimedia,which needs real-time transmission,multi-point communication and packet communication of speech for achieving its good teaching result.With the development of DSP,it is applied to the digital language learning system to realize speech information digitization and digital communication networking.DMA is taken to read the hard disk,make the system performance good and achieve the full digital language teaching.
