Translation:My favourite thing is speaking Welsh.
I sympathize. I'm probably losing my hearing as well (I'm 51), but more importantly, I have never really invested in high quality speakers for my computer and I don't want to turn the sound on loud on my phone, so I have the devil of a time with these auditory exercises.
You speak into the microphone of your computer or phone and it gives you a few chances to get it correct. As I recall, it says the phrase for you first, and then you have to repeat it. It was somewhat frustrating on the Portuguese, but I tended to do that on the computer, so I was sitting farther away form it. The German I mostly did on my phone, and it worked swimmingly. Of course, it is just as possible that my Portuguese pronunciation is just not as good as my German. I believe it was used on the Spanish and French as well, but I cannot remember them, so they must have worked so smoothly I didn't even notice them. I imagine, though, that they function because of easily available word recognition software, and that may simply not exist for a language like Welsh.
