Real-time implementation of cochlear implant speech processing pipeline on smartphones

摘要

This paper presents the real-time implementation of an adaptive speech processing pipeline for cochlear implants on the smartphone platform. The pipeline is capable of real-time classification of background noise environment and automated tuning of a noise suppression component based upon the detected background noise environment. This pipeline was previously implemented on the FDA-approved PDA platform for cochlear implant studies. The paper discusses the steps taken to achieve the real-time implementation of the pipeline on the smartphone platform. In addition, it includes the real-time timing as well as the noise suppression results when the entire pipeline was run on the smartphone platform.
