It does not mention it anywhere if I can use those voices in such way for commercial purposesĪgain, maybe I’m overcomplicating this, but I would prefer something that explicitly grant me permission to use the audio files in commercial projects. And the some goes for all voices I can install. In case what I’m working on is going to be a success, I don’t want Microsoft coming after me because I did not have the rights to use the voices outside Windows. Maybe I’m only overcomplicating this, but since Balabolka is using the Windows SAPI and the Windows voices which is to my knowledge is free to use in a Windows application but because I do want to use the voices also on Linux, Mobile and in the browser, I’m not entirely sure if that would be ok to do.
