As I recall, there was an comment at the end of the included application
notes listing an address where you could request the additional application
notes necessary for using external ROMs.  I would suspect that the ROMs
contain rule tables (such as the examples given in the application notes)
which translate word fragments (or whole words) into the allonemes (?sp)
required by the speech chip.
