The parameters should be vowel specifications (four parameters each) in the following format:
- IPA of the vowel
- Openness of the vowel, as a number between 0 (fully closed) to 1 (fully open). A decimal number or fraction can be given.
- Backness of the vowel, as a number between 0 (fully front) to 1 (fully back). A decimal number or fraction can be given.
- Degree of roundness, as a number between 0 (unrounded) and 1 (rounded), which are the only currently supported values. Intermediate values can be supported later if needed.
