A learning data generating apparatus receives first training data, first correct answer information, and second training data, inputs the first and second training data into a neural network to thereby cause the neural network to output first and second array groups each constituted of a plurality of arrays, identifies a first array from the first array group based on the first correct answer information, the first array being an array corresponding to the recognition target, and compares the first array and each of the plurality of arrays constituting the second array group, to create second correct answer information corresponding to the second training data.
