Word board

A word board or communications board is a simple means to help people who have lost the ability to speak. A word board may typically be provided to those recovering after a stroke.
To communicate, the user points at the relevant words, letters or symbols on the board. Typically the following are included:
Yes |No | (☺) | 
ABCD EFG
HIJK LMNOP
QRS "X" TUV
& WX ? YZ
Why|What|When|Where 
There are now sophisticated electronic speech synthesis devices available for this purpose.
