Downton Abbey's Lady Mary is now the most in-demand British voice in America, new research has revealed.
Actress Michelle Dockery's cut glass English tones beat the likes of quintessential English actor Hugh Grant and current James Bond Daniel Craig, to become the most requested UK accent for the US voiceover industry.
Voiceovers are big business in America covering everything from TV ads to recorded birthday greetings and at the moment famous British - and Irish - voices are particularly popular.
From Nigella Lawson's sultry tones to Liam Neeson's Ulster brogue and even Gordon Ramsay's angry rants, demand has more than doubled in the past year.
Copycat versions of these, and others from Hugh Grant to Keith Lemon, are used for all kinds of things including online guides, training videos and even automated voicemails.
And Lady Mary's cut-glass upper-class accent is the most popular of the lot, according to PPH's analysis of 5,000 job adverts requesting British-sounding voices in the USA.
It does not even mean using the real voice of Ms Dockery who plays the aristocrat in the successful series, said PPH boss Xenios Thrasyvoulou.
Instead, a good impression will do as it will for others on the top 20 list including Daniel Craig and Helen Mirren - familiar to Americans for playing James Bond and The Queen.
All the Americans want is an English-speaking voice that sounds like the star or, sometimes, more generically they will ask for a 'BBC News' or a 'Downton Abbey' accent, according to research by global freelance marketplace PeoplePerHour (PPH).
Colin Farrell, the Irish actor who is a Hollywood A-lister is high in the list alongside Scot James McAvoy, who has also had success in American movies.
Surprisingly, Cheryl Fernandez-Versini's Geordie accent is often requested, even though her failure as a US X-Factor judge was attributed to US audiences unable to understand her.
Americans request British and Irish voiceovers more often than that of any other nation, said Xenios Thrasyvoulou and it is fast becoming a major UK export across the Atlantic.
Often they will request a 'Downton accent' or a 'Hugh Grant' or even a 'BBC News accent' when advertising for the service, said PeoplePerHour's research.
It may be for promotional or training videos made by private companies or even for novelty purposes like a 'celebrity' voicemail on a mobile or landline telephone.
Around 10.4 million Americans regularly tuned in to watch the last series of Downton Abbey shown over there and similar numbers enjoy Sherlock and Doctor Who.
But it is not just America. PPH found requests for British voices from countries as far afield as Australia and India to Mexico, Egypt and even Germany.
Xenios Thrasyvoulou said: 'The original British export was manufacturing then it was financial services now it seems to be the British accent.
'With more companies than ever across the world utilising videos for promotional purposes, voiceover artists from the UK are cashing in on the popularity of their accents.
'It's not just companies either, it seems that people from America, Australia and the UAE are also hiring voiceovers for novelty projects like birthday messages.
'The is potentially driven by a new wave of British programmes that are becoming hugely popular in the US and other countries across the world.'
