We would also like information on this. We would like to develop an Australian English voice.

The whole system and the level of accessibility of it impresses me, however, there is a problem: I am from Ukraine and I need Russian and Ukrainian synthesizer to fully utilize my macbook at university and for daily use. I discovered that there exists paid Russian voice for mac from Assistiveware which costs 108 euros and isn't usable in multilingual environment (mixed Cyrillic and English texts). And there is not Ukrainian synthesizer at all.
