Capabilities of the CCi-Mobile Cochlear Implant Research Platform for Real-Time Sound Coding

Abstract

One important obstacle to optimizing fitting and sound coding for auditory implants is lack of flexible, powerful and portable platforms that can be used in real-world listening environments by implanted patients. The clinical processors and the typically available research tools either do not have sufficient computational power and flexibility or are not portable. In response to this need, the Center for Robust Speech Systems (CRSS) at the University of Texas at Dallas has developed CCI-Mobile, in collaboration with the Laboratory for Translational Auditory Research at New York University School of Medicine and the Binaural Hearing and Speech Laboratory at the University of Wisconsin-Madison. The CCI-Mobile platform provides unique flexibility to implement a variety of real-time sound coding algorithms in real-world environments, including algorithms that require synchronized binaural stimulation. In this paper, we will describe the overall architecture of the CCI-Mobile platform and provide practical considerations for designing real-time sound coding algorithms with this platform. CCI-Mobile is under development and future generations may provide further functionality, beyond what is described in this paper.
