Ke$ha sometimes sings in a voice that exhibits "vocal fry."
Ever heard of the linguistic phenomenon called "vocal fry"? It's when someone's speech drops to a lower register and creates a hoarser, creakier sound. Think of the singing of Britney Spears or Ke$ha, or perhaps the actress Aubrey Plaza, who plays April on the show "Parks and Recreation." Vocal fry was once considered a speech disorder. But a new study from Long Island University found it is wide spread in female college students.
