I mean that instead of solely 'Helo Dewi Lingo,' 'Helo Duolingo' should be accepted. In the forums, they specified that instead of 'Dewi Lingo,' you could use 'Duolingo,' that's all.
You should also have 'Helo Duolingo' accepted.

It sounds like Stewy not Dewi. The audio of the welsh lessons is definitely worse than the other languages. It's a shame they can't get it more accurate and less robotic.
