Real-Time Embedded Implementation of the Binary Mask Algorithm for Hearing Prosthetics
Valerie Hanson, Kofi M. Odame · IEEE Transactions on Biomedical Circuits and Systems · 2013
In this paper, we present a real-time embedded implementation of the binary masking algorithm, which has been shown to significantly improve speech-in-noise intelligibility. Our real-time implementation relies on a balance of parallel processing and hardware pipelining. We have tested and evaluated our implementation on a Spartan 3A FPGA. The measured latency was 8.5 ms . The highest measured improvement in short-time objective intelligibility was 85%.
