Malala Yousufzai, 15, who was shot in the head by the Taliban, is said to be getting "better day by day" after successful surgery on her skull and ear.
The teenager escaped death by a matter of inches when she was shot on October 9 last year, the bullet entered her skull just above her left eye and ran along her jaw, "grazing" her brain.
She said: "Today you can see that I am alive. I can speak, I can see you, I can see everyone and I am getting better day by day.
"It's just because of the prayers of people. Because all people - men, women, children - all of them have prayed for me.
"And because of all these prayers, God has given me this new life, a second life. And I want to serve. I want to serve the people. I want every girl, every child, to be educated. For that reason, we have organised the Malala Fund."
Her message was recorded just before her latest operation at the Queen Elizabeth Hospital in Birmingham over the weekend.
She spoke of her hopes for the future and the work she intends to undertake through a charitable fund which has been created and which bears her name - the Malala Fund.
