What is a speech device? A guide for parents and caregivers

A speech device (AAC aid) supports communication when speaking is difficult. What it is, who it is for, and how TWIYO can help as an affordable alternative.

A speech device — also called an AAC aid (Augmentative and Alternative Communication) — helps people who cannot or struggle to speak. With a digital communication board you choose words and images; the device or app speaks them aloud. That makes wishes, feelings, and questions clearer.

Speech devices are used by children and adults with various causes: autism, speech-language difficulties, aphasia after a stroke, intellectual disability, or other neurological conditions. Not everyone who uses little spoken language needs the same aid — a speech therapist helps determine what fits.

Professional speech devices are often dedicated hardware with specialized software. They can cost thousands of euros and sometimes are obtained through reimbursement or assessment. That process can take time. Many families look for a way to practice communication with pictures at home in the meantime.

TWIYO offers an affordable alternative on a tablet or phone you probably already own. With the Premium communication board (AAC) you tap categories and words; the app speaks sentences aloud. You can add your own photos — of family, school, or daily activities — so communication feels more personal and recognizable.

TWIYO was born from our own experience with a non-verbal child. We saw how much our son understood when words were linked to images. That is why we built an app where you choose the pictures yourself — one that grows with the user.

Important to know: TWIYO is an educational and communication app, not a medically certified device. It does not replace a professional speech device or speech therapy advice. It can be a low-threshold way to practice at home, or a supplement alongside therapy.
