Also known as creaky voice, it involves elongating certain syllables so that they vibrate at the back of the throat, creating a tapping sound like a stick running along a railing.

With vocal fry, the phrase ‘no way’ becomes ‘no waaaaaaay’ and ‘whatever’ turns into ‘whateverrrrrr’.

An experiment by university researchers found 86 per cent students tested vocal fry in normal speech when asked to repeat a list of made-up words.
