Examples from several areas of cochlear implant research are presented, with emphasis on the continuous interleaved sampling (CIS) approach to speech processor design. Within-subject comparisons of such processors with the compressed analog (CA) approach of the clinical Ineraid device are reviewed, and ongoing similar comparisons with the clinical Nucleus spectral peak (SPEAK) strategy are outlined. Correlations between chronic performance levels with clinical CA processors and initial performance levels with CIS, data on further improvements in performance with chronic use of CIS, and instances of substantial benefit from custom fitting of CIS parameters are presented as examples of findings with immediate clinical implications. New studies are described, involving the measurement of intracochlear evoked potentials in response to cochlear implant stimulation, and the integration of such work with computer modeling studies.
本文介绍了来自人工耳蜗研究多个领域的实例，重点是语音处理器设计中的连续交错采样（CIS）方法。回顾了此类处理器与临床Ineraid设备的压缩模拟（CA）方法的受试者内比较，并概述了正在进行的与临床Nucleus频谱峰值（SPEAK）策略的类似比较。将临床CA处理器的长期性能水平与CIS的初始性能水平之间的相关性、CIS长期使用后性能进一步改善的数据以及CIS参数定制拟合带来显著益处的实例作为具有直接临床意义的研究结果示例进行了展示。还描述了新的研究，包括测量人工耳蜗刺激引起的耳蜗内诱发电位，以及将此类工作与计算机建模研究相结合。
