I'm looking for a text-to-speech app for MacOS X that produces output that can be used in freely-distributable non-commercial projects that will be distributed online. Here is the problem with Apple's text-to-speech voices. From Apple's recent OSX licenses (Apple - Legal - Software): Meaning that Apple does not seem to allow such a use of its text-to-speech voices. I want a text-to-speech app that has an English voice with a non-native accent. The Indian-English voice of several TTS voice collections, like Apple's, is the sort of voice that I want, though I'd be willing to use other non-native accents. The collections that I've found have only female Indian-English voices, but that is no problem for me.
