It depends on how you translate a word, for example:
% s in this form is not a cell, but a character array
s=['A' 'A' 'A' 'B' 'B' 'A']
s = 'AAABBA'
ans = 1×6
1 1 1 2 2 1

Are the inputs always single characters? Are the inputs only A or B? Are the inputs always letters? Does case matter?
Here's a start for a method. It's compact and case-insensitive, but note that the outputs will probably be unexpected if the inputs aren't letters or single characters.
bunchofletters = {'A' 'A' 'A' 'B' 'B' 'A'};
bunchofnumbers = double(lower([bunchofletters{:}]))-96
bunchofnumbers = 1×6
1 1 1 2 2 1
Without knowing what the requirements are, I'm going to leave the task of making it fit for purpose up to someone who knows what the purpose is.
