Millions of young women are keeping up with their favourite celebrities ... by speaking like them.
Scientists have found fans are adopting a croaky drawl known as "vocal fry", copying US stars like Katy Perry and the Kardashian family.
The phenomenon may be down to women thinking that lower voices make them seem more masculine - allowing them to compete with men in the workplace.
Also known as creaky voice, it involves elongating certain syllables so that they vibrate at the back of the throat.
