Short description

The electro-larynx (EL) is a hand-held, battery-driven device. It is one possibility to regain speech for people who had to undergo an operation, where the larynx and the containing vocal folds were removed (typically due to larynx cancer). The device is held against the throat and its vibrations are transmitted through the neck. Then the patient can create speech by modulating the energy in the vocal tract.

We are in the process of designing a new speaking aid that improves significantly on the current state-of-the-art. One issue is how to give users who are usually skeptical towards technology the possibility to find their optimal voice sound. One idea would be to design something that makes fun.”
