That's puzzling. I don't get that here, it only raises the pitch of the
capitalised words.

I'm unsure exactly how to announce an apostrophe, which differs from
other punctuation in that it's inside a word rather than between them. 
For example, how should it say: "isn't"

Should it split it into two "words",
"isn't" =  "isn apostrophe tee"
"you'ld" = "you apostrophe el dee"
sometimes the fragments may be unpronounceable.

Playing a recording faster would be tricky, probably needing to run
"sox stretch".  Truncating would be easier :-)

Yes, I'll do that.

Thanks. I've found the problem now.  It also affected [v] and [D] (as
in "then").
