Might be a really simple question, but does anyone have any tips for how to make a vowel sound more nasal/harsher? Specifically, I'm working with Miku English. She's singing the word "and" (Whose phonemes are { n d ). Checking Vocaloid Wiki, { seems like the harshest/most "a"-like "ah" sound, but she's pronouncing it with more of a rounded or "o" sound (like a rich, really cultured woman or something, ha ha). I've tried splitting "and" into two syllables to get "a" by itself, splitting it away from the preceding lyric a little, messing with dynamics/velocity...but she really likes her rich-person's "ah." Any suggestions? She sounds sort of like "on;" I'm looking more for the "a" sound in "apple."
