Many solfeges have been devised, for example those by Erv Wilson.
Backwards-compatible solfeges
These expand on the conventional solfege. They use the 7 traditional consonants D R M F S L T. They use the traditional vowels plus new ones. See 19edo solfege, plus Andrew Heathwaite's solfeges for edos 17, 22, 31 and 41, and xenwiki user Phylingual's solfeges for edos 26, 29 and 53.

Uniform solfeges
These are closely related to ups and downs notation. They are particularly good for large edos like 41 and 53. They are also for rank-2 temperaments. To the 7 traditional consonants are added 6 altered consonants. The vowels are non-traditional. There is a uniform vowel sequence for all degrees, hence the name.

Numeric solfeges
These are good for small edos that aren't heptatonic-friendly, like 5, 6, and 8-11. An 11-edo example:
