This totally puzzles me. I wrote about the language and regioncodes of the installed voices on my iBook. They all returned '0', and I assumed that this meant 'unknown'. That turns out not to be true.
I downloaded and installed Acapela Multimedia HQ TTS [acapela-group.com] this morning, and now I have all of their available TTS languages installed. Simply querying the Language and region for each installed voice returns a strange list, and I can't find a complete list of all codes anywhere, so help is greatly appreciated. This is the list I have so far:
0 English 0 both UK and US
1 French 1 France
2 German 3 Germany
3 Italian 4 Italy
4 Dutch 5 Netherlands
5 Swedish 6 Belgium
6 Spanish 7 Sweden
9 Norwegian 8 Spain
34 Belgian Dutch (Flemish) 12 Norway
Does anyone have a complete list of these codes and their meaning?
