Hey there
That is good news, my sister-in-law's dad had a stroke about 2 years ago but more than just his swallowing and speach was affected, all one side of his body had been paralyzed.
With physical and speech therapy he is up to a faint whispering talking ability but the great thing is that he can communicate, laugh, smile and even ***** if he wants to, he is also on soft baby type foods and no longer needs the feeding tube inserted into his belly.
He is just so happy to be alive and has made this progress, to not be able to talk is hell, so while gram is re-habbing just be good coaches of encouragment while it is hard for her right now, but I am sure you will be an inspiration to her anyway
May you all take care now,
** hugs for health **
