Sonus: AAC Talker & Speech Aid

Sonus gives a voice to anyone who finds spoken words difficult. Tap a picture, hear it spoken aloud — it's that simple. Built for children and adults with autism, apraxia, Down syndrome, aphasia, stroke recovery and any condition that makes talking hard.

Sonus is an AAC (Augmentative and Alternative Communication) app that turns symbols into speech. Tap cards one by one to build a sentence, then let the natural-sounding voice say it for you.

WHY FAMILIES AND THERAPISTS CHOOSE SONUS

• Core communication is completely free. Tapping cards, speaking sentences and the ready-made categories will never be locked. We don't believe a child's voice should sit behind a paywall.
• Ready to use in seconds — open the app and start talking, no setup required.
• Beautiful, high-contrast cards that are easy to recognize.
