Phonak AG - Roger On™

About the Project

Roger On™ is an intelligent wireless microphone designed for everyday use, specifically developed for conversations with background noise and/or increased distance. The captured speech is transmitted directly to the hearing aid, allowing people with hearing loss to participate more easily in conversations. Key features of Roger On include left-right speech recognition and automatic mode selection depending on the environment and usage scenario.
