Is "Are you eating bread?" really wrong?
Nope it should be accepted, report it.
" Do you like eating bread" is surely acceptable?
Why should it be acceptable?
There is nothing in the Welsh sentence that talks about "liking".
Is it me or is the TTS saying "baro" instead of "bara"?
Yeah it does sound like that. Just ignore it since the contributors can't do much about it. If you're not sure of a pronunciation then please feel free to ask :).
