An American girl has become an internet sensation after a video of her pronouncing any word her friends say to her backwards almost instantly.

Alyssa from Oklahoma has notched up nearly two million views after the bizarre video shows her pronouncing even the longest of words backwards.

She manages to get her lips around words such as "inihgrobmal" and "epocsodielak" - the high-end Italian carmakers Lamborghini and kaleidoscope pronounced backwards.

In the video, her friends shout out random words and she effortlessly repeats them backwards.

Her friend filming the video explains Alyssa's weird talent as it begins: "Anyone can say a word to her, and she can say it backwards within three seconds."

Alyssa even manages a few phrases and reverses "Panama City Beach" to "Hcaeb ytic amanap" almost instantly.
