Somehow, in someway or another, my voicebank does this:

Im using openutau, JA VCV phonemizer on a CV voicebank, with VV phonemes for smoother vowel transitions. Any other vowels seems fine, but "a i" for some reason gets somewhat static and unnatural. I tried deleting the .frq file and it wont regenerate, anyone know how do you fix this problem??????
