Ed has lost his eyesight and he needs to get a phone. Is there a utility that will record numbers into his phone by voice? Leo says that if Ed brings his old phone to the phone store, he can ask them to move his contacts into the new phone for him. Most phones have accessibility features, but Leo says that Apple does it best. But that's usually for calling.
For editing the contacts, that could be a challenge. Windows Phone's Cortana voice app is a brand new utility, so it may be able to edit entries with voice. It'll be a long process though.
