To determine a result of speech recognition in consideration of a user's re-utterance while maintaining accuracy of speech recognition.SOLUTION: A vehicle control device (1) includes: a voice acquisition unit (11) for acquiring voice data; a phrase identification unit (101) for specifying a candidate phrase; a reliability calculation unit (102) for calculating reliability of the candidate phrase; a number of times measurement unit (103) which measures a number of times of identifying the candidate phrase; a judgment value calculation unit (104) for calculating a judgment value based on the reliability and the number of identifying times; and a result determination unit (105) for determining the candidate phrase as a result of speech recognition, when the judgment value is equal to or more than a first threshold value.SELECTED DRAWING: Figure 1
