    The Macintalk driver uses the sound buffer in high memory to output its
words, the problem is that it refills the buffer continuously, so after
a sentance, all that would be in the buffer is the last part of it.
    If you want to be clever, all you have to do is write a program which
replaces the pointer to the sound routine in the jump table with a pointer
to a routine of your own.  When Macintalk wants to output the sound, it
calls you and you copy the sound buffer to a safe place, and then either
go ahead and call the original sound routine or return.  This is not a
dubious hack, it is the respected and correct way to modify a system
routine and is documented in Inside Mac.
