I believe MacinTalk Pro (Victoria, Bruce, Agnes) said "Drive", while
the other voices said "doctor". The other related case which we get
wrong is St. for street / saint.

Please file a bug. We plan to stay around for the long haul, and TTS
is an increasing focus in our work.

I can assure you that TTS has been anything but "untouched", and I
have CVS logs to prove it :-)
Unfortunately, we have noticed that many TTS improvements are not
evident unless you play the old and new versions side by side. For
instance, 10.2 featured a completely rewritten intonation model that
sounded much better than what we had before. 10.3, as you mentioned,
featured the Vicki voice, and 10.4 featured across-the-board
improvements in the signal processing, especially related to speaking
at very fast rates.
