Is it just me or is it really hard to understand the way "y sêr" is being pronounced here?
She isn't actually saying 'the Moon' but it isn't very clear, you can check it out on the Ivona website, which is where the voice originates. Sorry there is at present nothing we can do to alter this since Duolingo tells us they can't alter individual sound files. If they do let us alter it then we would try the other Ivona voice for this word since it sounds a lot better.
O'n i heb sylwi ar wall pan roeddwn i'n defnyddio ac wedi gorffen y cwrs ar yr wefan, dim ond ar yr ap.
In the android app the TTS is saying "see-arr" instead of sêr (August 2018), but definitely not "lleuad".
