- And what's your name?

- Uh, Mandy Harvey.

- And who is this?

- (Mandy) My interpreter.

- (Simon) What is your name? - (interpreter) Sarah.

- (Simon) Nice to meet you, Sarah. - Nice to meet you, sir.

- (judge) Hi, Sarah. (applause)

- (Simon) Okay, Mandy, so I think I've worked this out.

So you're deaf?

- Yes, I lost all my hearing when I was 18 years old.

(audience awwing)

- Wow, and how old are you now?

- Uh, 29. So it's ten years.

- Wow.

And, Mandy, how did you lose your hearing,

if you don't mind me asking?

- I have a connective tissue disorder,

so, basically, I got sick and my nerves deteriorated.

(audience awwing) ♪ (sentimental music) ♪

(audience applauding and cheering)

- (Simon) So you were singing before you lost your hearing?

- Yeah, I've been singing since I was four,

so I left music after I lost my hearing,

and then figured out how to get back into singing

with muscle memory, using visual tuners

and trusting my pitch.

- So your shoes are off because you're feeling the vibration.

Is that how you're following the music?

- (Mandy) Yeah, I'm feeling the tempo, the beat,

through the floor.

- And, Mandy, what are you going to sing?

- I'm gonna sing a song that I wrote called "Try."

- (audience member) Woo!

- Okay, can you tell me what it's about?

- (Mandy) After I lost my hearing, I gave up

but I want to do more with my life than just give up, so...

(audience cheering wildly)

- (Mandy) Thank you.

- (Simon) Good for you.

Okay, well, this is your moment, and good luck.

- Uh, okay.
