"Bishop takes knight" is a phrase that follows the rules of descriptive notation and not of algebraic. Voice control recognizes and uses this type of phrase because of its naturalness to players. So we should let files be named according to descriptive notation, because it is more natural to say "queen pawn" or "knight pawn" than to recall "delta" and "bravo" from the NATO phonetic alphabet which has nothing to do with chess. The only word missing from the vocabulary to enable this is "to", as in "pawn to queen four".
