id pronounce it vee-oh-la
I pronounce it Vee-oh-lah and the only [name_f]Viola[/name_f] I’ve met pronounces it Vee-oh-lah.
I say it more like Vi-ole-uh actually! I love Vy-luh, but definitely wouldn’t pronounce it that way
I’ve decided this name is more confusion than it’s worth 
[name_f]Viola[/name_f] (vy-oh-la). [name_f]Veola[/name_f] (vee-oh-la). Vylah or Vilah or Vyla or Vhyla for (vye-la).
