computer telecommunication integration(CTI) technology is the integration of computer science,electron and communications discipline,and is suitable for practice training.However,the present CTI experimental scheme does not have open interface and is weak in secondary development.To solve this problem,we proposed a combination of hardware and software voice processing platform based on DSP processor,which has full open access to hardware and software interface,and is suitable for secondary development.Moreover,this platform is suitable for telecommunication,voice signal processing and innovative experiments,hence it is useful in course design,summer internship and graduation design,for the development of students' innovation ability and engineering capability.%计算机电信集成(CTI)技术是计算机、电子和通信等学科领域的交叉融合,非常适合用于实习实训环节,但现有的CTI实验方案存在硬件资源不开放、二次开发功能弱的缺点.针对这一问题,提出了一种以DSP为核心的硬件语音处理模块设计思路,并结合计算机端的软件单元,组成完整的CTI解决方案.其特点是全面开放的硬件资源和软件接口,具备强大、灵活的二次开发功能.可以实现电信类、语音信号处理类和创新性实验,适合课程设计、暑期实习、毕业设计等环节,有利于培养学生的软硬件综合开发能力以及创新思维和创新能力.
