Two years ago，Wendy Hasnip，47，experienced a brain injury that left her speechless for two weeks. When she finally recovered. she found herself talking with what seemed to be a French accent.”I phoned a friend the other day. and she spent the first ten minutes laughing.”Hasnip said at the time.”While I have nothing against the French. ”
Hasnip suffered from foreign accent syndrome（外国口音综合症），am condition in which people find themselves speaking their own language like someone from a foreign country. The condition usually occurs in people who have experienced a head injury or a stroke（中风）一a sudden loss of consciousness，sensation，or movement caused by a blocked or broken blood vessel（血管）in the brain.
The condition was first identified during the Second World War in a Norwegian woman whose head was injured during an attack by the German military. The woman recovered but was left with a German-sounding accent. to the horror of fellow villagers who avoided her after that.
Researchers have discovered that the combined effect of the damage to several parts of the brain makes victims lengthen certain syllable，mispronounce sounds，and change the normal pitch（音高）of their voice. Those changes in speech add up to what sounds like a foreign accent.
Another researcher，a phonetician（语言学者），says victims of the syndrome don’t acquire at me foreign accent. Their strangely changed speech only resembles the foreign accent with which it has a few sounds in common.
When an English woman named Annie recently developed foreign accent syndrome after a stroke. she spoke with what seemed to be a Scottish accent. However. Annie’s Scottish coworkers said she didn’t sound at like a Scot.
