Seventy channels in the UK currently provide subtitling services, according to watchdog Ofcom.

Most of these air pre-recorded programmes - for which, subtitling can be prepared in advance.

This means that subtitles can be synchronised to images, edited to a reasonable reading speed and checked for errors.

However, live programming and some pre-recorded programmes have to be subtitled live - leaving them prone to mistakes.

These subtitles are delayed by several seconds and typically scroll across the screen.

Source: Its hilarious attempts at janet, jazz, jazz and jam left those watching the programme with subtitles scratching their heads as they tried to work out what was actually being said.

And it isn't the first time the BBC has misspelled a name to amusing effect.

The broadcaster has previously referred to Italian prime Minister Silvio Berlusconi as 'Mr Beryl Beryl' - while Labour leader Ed Miliband became 'Ed Miller Band'. 

Meanwhile, former chief medical officer Sir Liam Donaldson was once dubbed 'Silly and Admundsen' - with the National Union of Students renamed as the National Union of Stew Departments.

Other blunders have seen the Ireland rugby team referred to as Island, the sale of millions of puppies - not poppies - in Britain on Remembrance Day, a 'cat's pornography reading' disclosed during a court report and a solemn call for silence become 'a moment's violence' during the Queen Mother's funeral in 2002.

During one particularly toe-curling moment, many viewers would have been left wondering how a man could have possibly named his 10-year-old son 'phrase whore' - only to realise his name was actually 'Fraser'.

And when one BBC announcer revealed the Government was ‘making helpful decisions', deaf members of the audience would have been confused as to why politicians were ‘making holes for surgeons'.

The embarrassing gaffes are not just restricted to the BBC's News and Sports channels - with one of the broadcaster's Weather presenters previously subtitled as saying: 'they would be a few more mist and Fox patches'.

And most of the blunders have not gone unnoticed with the public - with celebrities also picking up on the bizarre mistakes.

In June last year, Dr Christian Jessen tweeted: 'The typos on BBC news subtitles are quite funny sometimes. Today "500 actors are set to be killed" later corrected to "500 badgers". Phew!'

However, the BBC is not the only broadcaster to have suffered hilarious subtitle gaffes - with 70 channels in the UK now providing a subtitling service.

ITV has previously misquoted Eurovision star Engelbert Humperdinck as 'engle Bert humper distinct', while This Morning once accidentally confused the word 'rate' for 'rape' during a fashion segment.

Last year, Ofcom demanded that broadcasters monitor the quality of subtitles, which are used by more than a million people, every six months for two years.

A consultation which started in May suggested that problems began when pre-recorded programmes were delivered to broadcasters too late to allow subtitles to be prepared in advance.

Ofcom will publish a report based on its findings in spring 2014, and use the evidence to decide is changes to the current guidelines are needed.

A BBC spokesman said: 'We recognise that subtitling is a hugely important service, and we endeavour to ensure it is as accurate as possible.

'As with all broadcasters, there are occasions - particularly during live broadcasts - when mistakes inevitably occur, but we do all we can to keep this to a minimum and are constantly striving to deliver a reliable service.'
