The singer will release Standing Ovation: The Greatest Songs from the Stage on November 19. The artwork appears below.
The record includes renditions of 'Send in the Clowns' and ABBA's 'The Winner Takes It All' as well as a new twist on Judy Garland's 'Somewhere Over The Rainbow'.
"I have been a fan of musicals since I was a wee girl," Boyle said. "I love them and have enjoyed the drama and the range of emotions they inspire in you.
"I still remember the first time I saw Les Mis, my all time favourite. I fell in love with it and have seen it now countless times as each time you watch it you draw something different."
She also described working on the album as "a joy", adding: "[It] came very naturally as I knew the songs and could identify with the characters in the studio."
The 51-year-old, who has joined forces with producer Biff Stannard for the LP, has also collaborated with Donny Osmond on two tracks and Michael Crawford on 'This Music of the Night'.
Discussing the duets, she confessed: "Recording with Donny on two songs was a dream come true. Working with him was awesome and I learned so much from him as a performer and a person.
"Being in the studio with him was without doubt the best day ever - it wasn't work!"
The star's previous three albums have each topped the UK charts and sold over 18 million copies worldwide.
