The Toby Churchill SL35/Cherry is an assistive device that allows people without the power of speech to communicate with other people. It features dual displays encouraging face-to-face communication, and select models feature a voice synthesizer. A memory feature allows multiple phrases or speeches to be prerecorded and replayed multiple times.
After loosing the ability to talk Toby Churchill set out to design a portable communication aid using his engineering skills - creating a typewriter which instead of typing on paper, typed the message on a display, and this was then logically named the Lightwriter. Although having no plans at that time to make more than just for himself but, as he met other people in a similar position, realised that there was a demand for them and started to manufacture them for other people, founding the Company in 1973. This model dates from the 1990s.
