My dad is hard of hearing and the issue continues to get worse, though his hearing aids do help some. I’ve been looking for an app that could take what’s being spoken — in real-time — and write it out for him on a device (iPad, iPhone, other). But the WiFi network is not available at the retirement home where he’s at. So this needs to work off of a cellular connection. If you know of some solid apps in this regard, please leave a note in the comments section. Thanks!
