A voice recognition processing apparatus comprising: a voice acquirer configured to acquire a voice uttered by a user, to output voice information and to measure a length of time uttered by the user based on the acquired voice to create utterance duration information; a first voice recognizer configured to convert the voice information into first information; a storage device (270; 370; 470) configured to previously store - a dictionary in which an acceptance object list and an exclusion vocabulary are registered, the exclusion vocabulary being a vocabulary except a vocabulary registered in the dictionary as the acceptance object list, and - utterance duration data corresponding to each word of the vocabulary included in the acceptance object list and indicating a length of time required for an utterance; and a recognition result determiner (204; 304; 404) configured to - compare the first information with the exclusion vocabulary to determine whether the first information includes a word that agrees with a word included in the exclusion vocabulary, - determine that the first information is information to be rejected, when the first information includes the word that agrees with a word included in the exclusion vocabulary; - determine that the first information is information to be executed, when the first information does not include the word that agrees with a word included in the exclusion vocabulary, and - regarding the first information that is determined not to include the word that agrees with a word included in the exclusion vocabulary and to be executed, read the utterance duration data from the storage device and compare the read utterance duration data with the utterance duration information created by the voice acquirer to make a second determination whether to reject or execute the first information, based on the comparison. a voice acquirer configured to acquire a voice uttered by a user, to output voice information and to measure a length of time uttered by the user based on the acquired voice to create utterance duration information;
