Dame Julie Andrews could be one of the first patients to receive artificial vocal cords that might restore her voice.
The-76-year-old, who lost her full vocal range after an operation in 1997, is being treated by a voice doctor.
The Mary Poppins star has visited a team of scientists who hope to test the elastic synthetic tissue on patients suffering from voice loss as early as next year.
She could potentially be one of the first patients to benefit from the injected biogel, which is designed to vibrate in the voice box like a real vocal cord.
The Sound of Music actress chairs a non-profit fund-raising organisation called The Voice Health Institute which is supporting the research.
Professor Langer, who has been developing the treatment, said of Dame Julie: "She's just a wonderful person and everybody in our lab really enjoyed interacting with her."
