I bought this app. The voices are american, it would have been nice if they had UK ones as well.
Not much difference in the voices (sexy or business), they sound like the same person.
Received a link for a new version, clicked on it and now I have no voices.
Suppose I'll have to wait for support to tell me what to do. No uselful information on the website. Don't bother trying to send a message to support from your blackberry, it doesn't work. You can only get through on a laptop/desktop PC.
Takes a long time to preview the voices and there's quite a lot of messing around to assign the tones.
Maybe these problems have been ironed out in the new version, I'll let you know if I ever get it.
Don't expect too much from this app !!!!
