Welcome to the Ouisper project website

There has been interest recently in the idea of a sensor-based system allowing speech communication via standard articulators, but without glottal activity ; that is, a silent speech interface.

Two distinct types of application can be envisioned :

an alternative to tracheo-oesophagal speech (TES) for persons having undergone a tracheotomy - a prosthesis for patients who have lost the use of their vocal chords.

a "silent telephone" for use in situations where quiet must be maintained, or for communication in very noisy environments.

The Ouisper project proposes to build a device for production of intelligible speech, from ultrasound and optical imagery of the tongue and lips - without activation of the vocal chords.
