Julie Andrews says her four-octave voice isn't coming back.

The Oscar and Tony Award-winning actress said in a recent interview that a botched operation to remove noncancerous throat nodules in 1997 hasn't gotten better. It has permanently limited her range and her ability to hold notes, according to the Huffington Post.

"The operation that I had left me without a voice and without a certain piece of my vocal cords," said Andrews, who starred in such quintessential stage and film musicals as "The Sound of Music," "My Fair Lady" and "Mary Poppins."

The actress says she can still speak "pretty well" and can still hit a few bass notes, "So if you wanted a rendition of `Old Man River' you might get it, but I'm not singing as much these days."

Andrews has sung in public since the operation, including in the 2004 film "The Princess Diaries 2: Royal Engagement" and in a 2010 London concert. But she called those "speak-singing."

So she's getting into hip-hop?

The 77-year old says she's devoting her time to her books and in directing theater.

Her latest children's book, "Little Bo in London: The Ultimate Adventure of Bonnie Boadicea" was just released by Harper Collins. It's the fourth and final book in the series about a possibly magical ship's cat that travels the world with the man who rescued her. It's the 27th book she's co-written with her daughter, Emma Walton Hamilton.

Andrews says, in a strange way, she feels fortunate about the ordeal because it has pushed her to find a "different way" of using her voice. Paraphrasing a line from her "Sound of Music" character Maria von Trapp, Andrews said "When one door closes another window opens."
