Over the summer I think they must have done something to the microphone used by the Leader of the Opposition in the House of Commons – Ed Miliband sounds very different these days, even Ann Treneman has commented on it. If it is something he has done deliberately – to sound more authoritative & mature? - then it does not have the same effect in other surroundings, on other microphones.
It is in some ways louder & clearer, cutting out the surrounding noise, but with a slightly muffled echo, distinctive & immediately recognisable, So much so that I was bemused to come across it suddenly on Radio 5 on Wednesday morning – I was only clicking through on the way to another station but stayed for a couple of minutes to confirm it - & remove my confusion over whether parliament was in recess.
