Depends which part of Wales you google. North and South differ widely and ' townies' have a very 'brash' sounding accent. The valleys accents vary as well. I have been told I have a soft, sing song Welsh voice, (unless I'm yelling at a child to put another one down).I had a conversation with Joe's mum a few days ago about how much I liked women with British accents and she corrected me. There is no such thing. Rather many different ones.
Now my inside Lyn voice might have a different sound as I read your posts.
What does an accent from Wales sound like. I'll Google it.
