Why is it that her articulation is gloriously perfect when she sings but rather blah and robotic when reading from wikipedia?

I've noticed I don't have the new voice at all.

Check Settings -> General -> Accessibility -> Speak Selection -> Voices -> [language] -> Enhanced quality.

Mine was already on. Also I don't know if it's relevant.

This is for speaking selections and not Siri. Mine is Off and I still hear Siri.
