That's interesting, Wendy, yes I do use voice to make calls but I DIDN'T know about answering calls. Let me tell you, I've missed quite a few or actually disconnected a few more trying to find the Answer button! I'm more likely to miss a FaceTime call than any but my family is quite patient and understanding and know I'll call right back. I'll check on YouTube or Doug at Hadley.edu for answering a call by voice.
Another voice thing I need to figure out is I'll ask Siri a question and I receive a lot of text answers (unlike Google who just tells me the answer albeit not much detail). I always think, "Siri, honey, if I could read comfortably I wouldn't have asked you!!" Need to find out how to have Siri's answers read aloud. Thank you, @Brown Eyed Girl
