Well, I shouldn't have any problem with learning Irish and its sounds! Awesome voice....I love humans. ;)
It almost sounds like there are two different speakers, though it could be just a lot of inconsistency in her pronunciation.
Just an observation! Really enjoying the course so far.
Id say the voice actress who did these was possibly from around the midlands or somewhere without a strong focus on irish. Most people here in the midlands say their buachaill like that unless a person is taking the piss out of a strong irish accent (my hatred on irish listening tests. Ulster accent sweetmercifulgod)
