It is a wonderful program. It works very well. But if you if you need a language other than English, it still performs, it works just fine. With just one issue. You can tell that it's not a native Dutch speaker, but rather an English voice speaking Dutch. And that doesn't sound good. I can't work with that commercially, can't make it work.

I contacted them, and the same day, a sprint was initiated. They handle that very well. The voice spoke much better Dutch. But it's still an English voice trying to speak Dutch. Almost perfect, but English. But as soon as abbreviations come up and the Dutch context is missing, it immediately switches back to English pronunciation. It seems like Open eLMS only wants to provide English voices. And they think they can succeed abroad with that. Unfortunately, that's not the case.
I would be happy to pay credits for installing a native Dutch voice (preferably a one-time payment).

I would love to give them five tacos, but that's not possible right now with a foreign language.

I cannot react on the reply. Strange.
Almost perfect but not usable in Dutch makes still 2 tacos. No-one told me that i can upload my own voice, when i asked for a solution. How to upload my own voice?
