Open Speech Platform

OPEN SPEECH PLATFORM AT UC SAN DIEGO

We are developing an open, reconfigurable, non-proprietary, wearable, realtime speech processing system suitable for audiologists and hearing aid researchers to investigate new hearing aid algorithms in lab and field studies. Through active collaboration between engineers and scientists, we aim to accelerate hearing healthcare research and facilitate translation of technological advances into widespread clinical use. See here for details.

This work is supported by the National Institute on Deafness and Other Communication Disorders, of the National Institute of Health (NIDCD/NIH). R01DC015436: "A Real-time, Open, Portable, Extensible Speech Lab" to the University of California, San Diego.

Architecture of the proposed system. The top pane shows realtime processes that consume no more than 10 ms end-to-end latency. The middle pane show low latency processes that can take 200-400 ms and provide noise suppression, speech enhancement, binaural processing, field data logging, etc. The bottom pane shows medium latency processes running on a user device such as a smartphone or a tablet for communicating with the wearable device.
