"Sometimes that is down to national pride, but it's also to avoid misunderstandings and protect nuance," says Kevin Hendzel, a former White House linguist.

前白宫语言专家凯文•亨德尔表示，“这关系到民族自豪感，也是为了避免误解，同时保留语言中的细微差别。”

US presidential translators will have passed security clearances, background checks and even sat polygraph tests, before they become privy to sensitive information involved in high-level diplomacy.

美国总统的翻译在获准接触高层外交中的敏感信息之前，必须通过安全审查、背景调查，甚至还包括谎言测试。

"There are no novices that work at the presidential level," says Mr Hendzel. "It takes a great deal of time for an interpreter to reach this stage. They are also experts in the subject matter, and they know getting a form of address wrong can be a deal breaker."

亨德尔称，“为总统工作的没有新手，一名翻译要经过很久才能做到这个级别。他们是这方面的专家，他们很清楚差之毫厘，谬以千里。”

'I am Hillary Clinton, honestly, I am'

“我真的是希拉里。”

"It's apples and oranges when you are comparing transitional calls by a president-elect to those of a head of state in the Oval Office," says Mr Yates.

耶茨称，“对比过侯任总统在交接期间的通话过程和成为总统后的通话后，你会发现两者完全没有可比性。”
