Originally there were separate glyphs for syllables ending in a nasal, such as don, with a long vowel, such as soo, with a diphthong, such as bai, as well as bili and sɛli.

The romantic "inscription on a house" that first drew the world's attention to the existence of the Vai script was in fact on the home of Curtis, a Cherokee.

If Curtis was informed about the Cherokee script, if he was already resident at Cape Mount by 1827/28, and if he made contact with any of the mission party at Big Town - Revey or even his Vai-speaking assistants – it is conceivable that the notion of a syllabary reached the Vai by this route – but perhaps not very likely.

Finally, whether the argument from coincidence should have any weight is difficult to say, but that two new scripts sharing the same basic structure, invented a continent apart within little more than a decade of each other, can each be linked, however tenuously (given the limited evidence), to the same individual, may reasonably be regarded as at least singular.

This roughly fifty page manuscript contains several now obsolete symbols:[11] The Vai syllabary was added to the Unicode Standard in April, 2008 with the release of version 5.1.
