Flex-5

Flex-5, or the Flex-5 System, is a vowel system that was considered on the vowel ballot.

Proposal
On April 30, 2017 at 18:30 UTC, Henry William proposed the system, stating:"I propose a 5 vowels system based on A-E-I-O-U where each main vowel has a more open and a more closed versions (/a/-/ɐ/, /e/-/ɛ/ and /o/-/ɔ/) and I and U have a vocalic and a semivocalic version (/i/-/j/ and /u/-/w/)."

Election
On May 6th, after having received fewer than 10 votes, the Flex-5 System did not advance to the second round. As such, the vowel system is not part of the demlang.
