Video: Deaf woman hears son's voice for first time This video was originally posted on YouTube by Amy's aunt, Catherine Arnold, in September, but has recently gone viral. It captures the emotional moment when the 26-year-old heard her father's voice, and that of her son Blake, for the first time. According to Ms Arnold, Amy is working hard to learn to "distinguish what sound is," and can now hear music as well as words. Every day is new and sometimes an exhausting experience. She loves the challenge to improve yet more and she is a joy to be around," she said. Footage courtesy of Catherine Arnold
