Just a follow-up to my recent post about the unsatisfactory section headed "Prosody and intonation" in Wikipedia's article on Vowels. I've removed quite a lot of this section and rewritten the rest, but kept the title Prosody and intonation. I hope that has improved it a bit. At least it now has a couple of references.
