A PDA-based research platform has been developed for implementing novel speech processing strategies and conducting psychophysical experiments with cochlear implant (CI) research that do not necessarily require real-time processing. The developed interface streams stimuli pulses to a CI unit in an offline mode from a Personal Computer via PDA platform using Windows Sockets (WINSOCK). Front-end of the application is run in MATLAB where stimuli pulses are created. Winsock establishes a TCP/IP connection with the PDA and starts the transmission of stimuli data. Server application installed on the PDA reads the stimulation data and forwards it to the SDIO board in packets where it is forwarded to the cochlear implant unit and pulses are then played in realtime. Versatility and flexibility are the key characteristics of the platform for easy implementation and testing of a wide range of applications and experiments without advanced programming skills.
已开发出一个基于个人数字助理（PDA）的研究平台，用于实施新颖的语音处理策略，并开展与人工耳蜗（CI）研究相关的心理物理学实验，这些实验不一定需要实时处理。所开发的接口使用Windows套接字（WINSOCK），通过PDA平台以离线模式将刺激脉冲从个人计算机传输到CI设备。应用程序的前端在MATLAB中运行，在那里创建刺激脉冲。Winsock与PDA建立TCP/IP连接并开始传输刺激数据。安装在PDA上的服务器应用程序读取刺激数据，并将其以数据包的形式转发到安全数字输入输出（SDIO）板，在那里数据被转发到人工耳蜗设备，然后脉冲被实时播放。通用性和灵活性是该平台的关键特性，无需高级编程技能即可轻松实施和测试广泛的应用程序和实验。
