Car crash leaves Australian woman with French accent

Perhaps not as amusing for the sufferer, but amusing to me considering they are otherwise unimpaired.
I wonder, though, if they really have an ‘authentic’ accent (meaning they make the same sorts of changes a native person with the accent would) or if they just sort of sound like they have the specified accent. Perhaps their voice patterns are changed by the injury and the perceived ‘new accent’ is just an artifact of how people hear them as altered.
