crytopie, I am praying for you and I am expecting much healing to come your way over the coming days!
There is a program called Sono Flex and a free version called Sono Flex Lite. This app can be put on your tablet and it allows you to converse easier using symbols and it produces spoken words. It can be setup easily for your needs. You may already have a program like this, and I hope you do.
My grandson has a rare syndrome that prevents him from understanding fully how to use this program, but he is progressing. Check it out on the App store.
God Bless!!
