British pop star Ed Sheeran is using a white board to communicate after he was advised to rest his voice between shows.

The Sing hitmaker is currently on tour in Australia, but he is having vocal problems, and has been ordered to stop talking when he is not on stage after seeing a specialist.

Sheeran writes in a post on Twitter.com, "Been told by the vocal doc not to talk at all between shows and they're giving me a white board to communicate with, could prove interesting."

The singer is in the middle of a run of three shows at the Qantas Credit Union Arena in Sydney before the trek moves on to Melbourne later this week (beg23Mar15).
