About us
Our vision
Watch in the video below how we want to enable you to speak freely in your daily life and work in the future.
Why are we doing it?
Whispp founder Joris Castermans has stuttered all his life.
“As a child and especially as an adolescent in high school, it bothered me a lot. I was shy, felt socially isolated and found it difficult to make friends.”
The Whispp team closely collaborates with speech therapists and other professionals to develop a solution for people with voice disorders.
Want to help?
The idea for Whispp that Joris had in 2018 finds its origin in the fact that when stuttering people whisper, they are relaxed and can speak (almost) fluently.
We then learned that Whispp is also valuable for people with a voice disability who lost their voice due to illness, trauma or old age people who need a boost for their voice.
