6(12) Vowel Creaky-Voice System

6(12) Vowel Creaky is a vowel system that was considered on the Vowel Ballot.

Proposal
The System was proposed saying: ''Six normal voiced vowels: i = i a = a u = ə w = u o = o e = e and Six corresponding 'creaky-voice' variants: î = ḭ â = a̰ û = ə̰ ŵ = ṵ ô = o̰ ê = ḛ Reasoning: 12 vowels allows lots of possibilities, not too out-there hard-to-pronounce vowels, and the creaky voice adds something different, to make the language more interesting :)''
