Yes, that's a bug. Thanks.

That was deliberate.  Ideally, "capital" would be spoken in the altered
voice in the same way that punctuation is, but that's difficult to
achieve at the point where capital letters are detected, so I thought
the sound icon might be useful to distinguish from an actual word
"capital" in the text.  I'll take another look to see if I can do the
altered voice instead.

That shouldn't happen, and I found no evidence of it in a test that I
did.

The "praat" program from  www.praat.org  is useful to analyse speech,
including a pitch trace.

I don't know anything about the use sound icons or sound icon packages,
although I noticed there was a directory  /usr/share/sound/sound-icons 
on my computer.  Perhaps recommended packages would be better
documented at the Speech Dispatcher level.
