Carly's Voice co-author offers insights into the way his autistic daughter Carly interacts with the world. She hears differently from most people--especially in terms of filtering multiple conversation. After Carly found a way to communicate, she must decide how to best use this voice to tackle her challenges. "We saw it as the beginning. Now that she could speak--what are you going to do with your voice? Life hands you whatever challenges it hands you, and what you do with that is the measure of who you are as a person."
