It sounds like she is in the bath and the device recording her is across the bathroom.
I don't really know how this report function works, but don't get rid of her - I think the accent is needed in order to better acquaint learners with it - but at least get her to re-record it.
Aye, a bug is preventing us removing the old sentence. At the moment there are two sentences recording that exist for it. There is a 50 / 50 chance of getting the new one. We need staff to fix the bug though before it can be removed completely. Listening exercises are disabled for the old file, but this is all we can do till staff fix the bug. We have a list of all sentences needing replaced, but our hands are tied ATM.
