There are three accents here: the narrator's 'own' voice, plus the two accents of the characters he's portraying.
I agree with Aisling that first character we hear is a rather exaggerated 'stage Irish', while the second character - the 'tempter' - is fairly posh southern English. To a native speaker's ear, these two accents are very obvious indeed.
The only point I disagree on is the narrator's voice. It is not English. In fact, it's a soft Scottish accent, possibly from Edinburgh. Listen to how he says 'eagerly' around 20 sec. - that's clearly a Scottish voice.
