our "blink method"

My sister has been unable to speak for about a month now. She is completely paralyzed except for her eyes being able to blink.
She can tell us a lot with our system. maybe it can help you.

She closes her eyes. We say “Vowel?” (if it isn’t she keeps them closed)
we split consonants up with the midway point being “m”.
If its not a vowel we say “beginning?” if it is she opens her eyes.
Then we begin. “b-c-d-f-g”…she opens her eyes. The first letter is “g”.
Then we start again.”Vowel?” she opens her eyes.
“a-e”…she opens her eyes. The second letter is “e”.
We begin again. “Vowel? (nothin) Beginning? (nothing) m-n-p-q-r-s-t” (she opens her eyes). “Get. is that the whole word?” She opens her eyes.
Then we start on the next word.
It is time consuming (but as she says, she’s not going anywhere) and sometimes we get messed up, but we’re getting better at it!
We try not to guess the word she is trying to say because then we get more confused. Just give it a try! Let me know how it goes!
