Give Voice
Back to Life
An AI-powered wearable restoring real-time natural speech — for anyone who has lost their voice.
The Human Cost
300 million people live without a voice.
Laryngectomy, ALS, stroke, paralysis — voice loss is not just medical. It is the slow erasure of identity, intimacy, and presence.
Losing a voice means losing the fastest way to be understood — at home, at work, in an emergency.
The Technology
Three steps to a restored voice.
Under the Hood
Speech AI built for the human body.
- Transformer-based neural text-to-speech.
- Voice personalisation from short recordings, where available.
- Designed for real-time, low-latency speech.
- Data encrypted in transit and at rest.
Who We're Building For
Three ways a voice goes missing.
People who can still produce some sound, but whose speech is strained, quiet or hard for others to follow.
People who lost their voice to throat cancer, a laryngectomy, or an accident, and who still have breath and throat movement to work with.
People who have never been able to speak, and for whom a voice has to be built from scratch rather than restored.
