The World Orthography (WO) is an alphabet and transcription system based on the Africa Alphabet and the International Phonetic Alphabet. In Daniel Jones’s 1948 Difference between Spoken and Written Language, an adaptation of WO for English is given with the letters a b c d ð e ə f g h i j k l m n ŋ o p r s ʃ t θ u v w x y z ʒ. The capitals of ð, ə, ŋ, ʃ, θ, and ʒ are: Ð (shaped like Ƌ), Ə, Ŋ (shaped like large ŋ), Ʃ (shaped like sigma Σ), Θ, and straight-bottomed Ʒ (shaped like reversed sigma).

In Normal English:

"This paragraph shows what English looks like in one form of World Orthography. It will be noticed that it is not possible to use for purposes of spelling an exact representation of the speech of any one English-speaking group, but that various adaptations have to be made in order to render the spelling usable by all sections of the English-speaking world. For instance, it is probably advisable to make the letter ə do duty for the sound ʌ as well as for the sound ə, in accordance with the speech of many in the North of England and in America who do not distinguish these sounds. Likewise, it will no doubt be found convenient to write most of the unstressed ə sounds with their present spellings, since they so often show relationships to other words, as in pedant, pedantic, provident, providential, method, methodical. Again, it will almost certainly be found advantageous to introduce a certain number of 'word signs' to denote short common words with variable pronunciation, for instance a, the, be, me, she, do, to, who. A limited number of words would have alternative spellings, e.g. pass, pass, grant, grant, salt, salt, again, again, with, with."
