Four-segment Alphabet was an IPA-based writing system invented by Julius Alfred Cordova of Iloilo City, Philippines. The best thing about this writing system is that it can fill all the areas of pulmonic consonant chart of the IPA, even the shaded areas with fewer diacritics, by simply combining two angles which indicate the articulation of a consonant. The upper angle indicates the manner of articulation and the lower angle indicates the place of articulation. For vowels the upper three segments indicate openness and the lower three segments indicate backness and roundness, and centralization. In addition, the numeral system is used to write and read fractions and decimals correctly and to avoid writing zeros.
Julius created this writing system to spell words phonetically and to identify the articulation of each letter. He also proposes that it could be used for other languages.

are endowed with reason and conscience and should act towards one another
in a spirit of brotherhood.
