The basis of phonemic pictures is—how could it be otherwise—the international phonetic alphabet ‘IPA’. The elongated ‘I’ ends in a stylized foundation outline.
To make things easier for those who are unfamiliar with the international phonetic alphabet or who may not know it at all, here is the re-transformation into the source language. In the case of phonemic pictures whose source language is not English, a translation into English is also carried out.
