Graphics and diagrams can be made available to blind users mainly in two ways: via speech descriptions or tactile printing. However, both approaches require help from a sighted, well instructed third party. We propose here a fast and inexpensive alternative to making graphics accessible to blind people, using sound and a corpus of ASCII graphics. The goal is to outline the challenges in sonifying ASCII diagrams in such a way that the semantics of the graphics is successfully brought to their users. Additionally, the users should have the possibility to perform the sonifications themselves. The concept is exemplified using circuit diagrams.
