I do not think that this is an appropriate question here. This place is for ANY kind of needs in gaming. Seeing that you can actually voice your characters with different speeds and freely with predefined voices can be usefull to someone.what exactly is this useful for?
I have tried all 3 websites. The best is naturaleaders but again, it is not free for commercial use so I cannot put it in the list. Also the fact that you cannot download the voice without using their software which is also limited to personal use, it's not quit fit for the free for commercial use. As for ttsreader, it only includes 2 languages, at least on the webpage, I did not go further. As for fromtexttospeech, I took ages to create my audio file and I gave up. So these can be good resources and to those that need them or want them I feel that these are good additions but I cannot add them to my free for commercial use list. Thank you VERY much for your contribution and I truly hope that some people will find this usefull!
