I think the producers or whomever "enforces the rules" of the game knew what she meant, she called the "G" to be there so she obviously knew it was there. She clearly had a regional accent of the type that sort of lops off sounds and muddies others (she over-pronounces "M" for example, perhaps to not get it confused with the already called "N".)
She was robbed, she called most of the letters on the board so she obviously knew the answer to the puzzle but she slightly (and not in an unusual way) mispronounces a commonly mispronounced suffix and she losses? Robbed.
I think an ounce of leeway should have been given.
