The voice recognition unit performs voice recognition. The evaluation unit inputs voice audio to be evaluated and a threshold value list in which a plurality of threshold values set individually for a plurality of predetermined words to be recognized serve as elements to the voice recognition unit, then uses the recognition results for the voice audio to be evaluated output by the voice recognition unit as a basis to calculate evaluation values for each of the plurality of words to be recognized, said evaluation values representing the recognition accuracy of each of the plurality of words to be recognized by the voice recognition unit that used the threshold value list. The display control unit causes a display device to display a threshold value adjustment screen for adjusting a threshold value corresponding to a discretionary word to be recognized among the plurality of words to be recognized. The threshold value adjustment screen includes an accuracy list screen in which the evaluation values calculated by the evaluation unit for each of the plurality of words to be recognized are presented together with ideal values calculated beforehand for each of the plurality of words to be recognized.
