no, charlotte church really did have some vocal problems. if you listen to her "enchanted" cd or "enchantment" or something like that, you can hear a wobble that's NOT vibrato that is a warning sign of vocal nodes.
i think they just had her singing stuff that was too big, too young and that she really did hurt her voice. she was incredibly talented, however.
