Thanks for reporting this, I'll try to look at it when I have
opportunity to work on speechd-el.

Looking at `speechd--voice-parameters' it seems it's an intended
behavior.  The reason may be that faces were assumed to be spoken in
different voices, while switching speech modes there was undesirable.
But your case makes perfect sense to switch speech modes on faces as
well.

You can try, as a quick hack, to add `punctuation-mode' to allowed
parameters in `speechd--voice-parameters'.
