Linephon   

Linephon alphabet was devised by Erik Moreno, a colombian teenager.
He devised it for create an “alphabeta franca” between all world’s languages.
The linephon name comes from the words line and
phoneme. Line because the letters are made with lines, and
phoneme because the letters are made in groups that correspond to the
articulation point of phonemes. For example, the phoneme group with a dental
articulation point is made up of t, d, θ, ð, s and z.
