Signia
German engineering. Own Voice Processing and fashion-forward design.
Signia, formerly marketed as Siemens hearing aids, is part of WS Audiology (which also owns Widex). Based in Erlangen, Germany, Signia is known for two distinctive innovations: Own Voice Processing (OVP), which makes the wearer's own voice sound more natural, and the Styletto — a slim, fashion-forward RIC design that broke with the traditional hearing aid aesthetic. The Augmented Xperience (AX) platform introduced split processing that handles speech and environment separately.

Signia technology: Own Voice Processing & AX Split Processing
Signia's most distinctive technology is Own Voice Processing (OVP) — a system that detects and separately processes the wearer's own voice in real time, making it sound more natural. This addresses one of the most common complaints from new hearing aid users: that their own voice sounds hollow, booming, or unnatural. The Augmented Xperience (AX) platform takes a split-processing approach, using two separate processors for speech and environment.
- Own Voice Processing (OVP) — most natural-sounding self-voice of any hearing aid brand
- Augmented Xperience (AX) — split processing for speech and environment on separate processors
- Integrated Xperience (IX) — latest platform combining AX with improved connectivity
- Styletto design — slim, fashion-forward RIC that resembles a wireless earbud
- Signia Assistant — AI-powered in-app support for real-time adjustments
- TeleCare — remote fine-tuning by audiologist via app
- Bluetooth LE Audio — low-energy streaming for iPhone and Android
- Signia app — volume, programs, OVP adjustment, hearing diary
