A useful and convenient means to analyze the radio frequency (RF) signals being sent by a speech processor to a cochlear implant would be to actually capture and display them with appropriate software. This is particularly useful for development or diagnostic purposes. sCILab (Swiss Cochlear Implant Laboratory) is such a PC-based software tool intended for the Nucleus family of Multichannel Cochlear Implants. Its graphical user interface provides a convenient and intuitive means for visualizing and analyzing the signals encoding speech information. Both numerical and graphic displays are available for detailed examination of the captured CI signals, as well as an acoustic simulation of these CI signals. sCILab has been used in the design and verification of new speech coding strategies, and has also been applied as an analytical tool in studies of how different parameter settings of existing speech coding strategies affect speech perception. As a diagnostic tool, it is also useful for troubleshooting problems with the external equipment of the cochlear implant systems.
一种分析言语处理器发送至人工耳蜗的射频（RF）信号的实用且便捷的方法是，使用适当的软件实际捕获并显示这些信号。这对于开发或诊断目的尤为有用。sCILab（瑞士人工耳蜗实验室）就是这样一种基于个人计算机的软件工具，适用于Nucleus系列多通道人工耳蜗。其图形用户界面为可视化和分析编码语音信息的信号提供了便捷且直观的方式。数值显示和图形显示均可用于详细检查捕获的人工耳蜗信号，以及对这些人工耳蜗信号进行声学模拟。sCILab已用于新语音编码策略的设计和验证，还被用作分析工具，研究现有语音编码策略的不同参数设置如何影响语音感知。作为一种诊断工具，它对于排查人工耳蜗系统外部设备的问题也很有用。
