Was Anita Ekberg dubbed?

Miss Ekberg's voice sounds different here than the way it sounded in Paris Holiday,the other film she made with Bob Hope, and in every other film I've seen her in. In fact, she sounds exactly the same as her 4 for Texas co-star Ursula Andress did in Dr. No. No surprise since Bwana was produced by James Bond producers Broccoli and Saltzman. Was Miss Ekberg in fact dubbed for Call Me Bwana?
