The British singer had to cancel tour dates in the US earlier this month after being struck down with laryngitis, and is believed to be planning to take preventive measures to stop it from recurring.
Voice coach to the stars Ron Anderson – who has worked with Alicia Keys, Joss Stone and Red Hot Chili Peppers - has apparently been enlisted to help teach the big-voiced star new singing techniques to keep her vocal chords in good working order.
A source told The Sun: 'There are commonly two approaches singers take. They are called 'singing through your chest' or 'singing through your head'. Singing through your chest can increase the chances of callouses and nodules appearing on the vocal chords. But the latter approach drastically decreases the chances of those problems occurring. Adele sings more through her chest at the moment.'
