Title:
DETERMINATION DEVICE, DETERMINATION METHOD, AND DETERMINATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/151503
Kind Code:
A1
Abstract:
According to the present invention, a re-ranking device (10) includes: a hypothesis input unit (12) which receives, as a plurality of series presented as a candidate of a solution to any one input, inputs of N best hypotheses that are results of voice recognition; and a determination unit (15) which determines a more accurate hypothesis among two hypotheses, by using N label re-ranking models represented in a neural network with respect to the two hypotheses among the plurality of hypotheses.
