Multi-Stream Architecture for Improved Conversation Performance

Hearing Review, November 03, 2023

RealTime Conversation Enhancement, introduced in the new Signia Integrated Xperience (IX) hearing aids, is based on a multi-stream architecture to provide a fundamentally new approach to analyzing multi-talker conversations. Further, given the way IX analyzes and processes speech, it is designed to provide enhanced benefit when the wearer engages in both one-on-one and dynamic group conversations. In this article, we explain the functionality of the technology, and we present and discuss data from a study demonstrating wearer benefit from RealTime Conversation Enhancement.”
