I came across these adverts: EPO 2013 EPO 2014 on TV a few years back and was curious as to what type of accent the speaker has. I've been told by a linguistic professor who is English that it is a 'posh' English accent but definitely would not be considered RP (Received Pronunciation), which is the standard accent used by broadcasters on the radio and on television.
The reason I ask is that I'm am a native English speaker who's accent and pronunciation have been 'muddled' by having moved through 4 different countries during my childhood. I'd like to improve my accent for personal and professional reasons perhaps entering the film or voiceover industry. I have a slight English/Irish accent but the pronunciations make some words difficult to understand and hopefully emulating a voiceover artist would help.
