1. A translation device comprising:
an internal state changing device; and
a generating device,
the internal state changing device comprising processing circuitry configured to:
change an internal state that is a final hidden state of an encoder, in a translation model that is a learned model constituted by an encoder-decoder model, as the translation model for translating an original sentence that is a sentence of a first language into a translated sentence that is a sentence of a second language,
change the internal state based on a random number,
set a numerical value range, and
change the internal state in multiple ways based on a numerical value included in the set numerical value range, and
the generating device comprising processing circuitry configured to:
input a desired original sentence into each of multiple translation models generated by the internal state changing device, and
generate multiple translated sentences in the second language corresponding to the desired original sentence.
