the story of a little boy. Two parents who never gave up. A delightful toddler who had no idea what he was missing out on. He could not hear. But tonight, you're about to see what happens the first time he hears his mother's voice. ABC's John donvan and our Phoenix affiliate ABC 15 with one boy's triumph. One boy who is America strong. Ascher! Ascher! Reporter: It was futile calling his name, because Ascher Goldberg, 2 years old, was born deaf. His own big voice among all the sounds he never heard. It's not that Ascher sensed anything missing. He didn't know what sound was. But his parents suffered the loss for him. Hey, I'm daddy. It was difficult. Reporter: They decided to give him some shot of hearing and went with a coke lee yard implacket. When it was switched on for the first time, it worked. That little startle response says that Ascher's brain was connecting with sound. Hi, sweetheart. Hi, baby. Reporter: And over the past six months, he's been figuring out that sound exists. And that it tells him things about his world. Like words. And even music. Because, well, watch this kid dance. As if he always had an ear for it. John donvan, ABC news, Washington. Hugging his mother when he hears her voice. We're all rooting for him tonight. Thank you for watching. We'll see you back here tonight. Good night.
