A string of acoustic feature parameters of each of recognition-desired words and a string of acoustic feature parameters of each of reception words are registered in advance. When an uttered word is received, a string of acoustic feature parameters is extracted from the uttered word, the acoustic feature parameters of the uttered word is compared with the string of acoustic feature parameters of each recognition-desired word, and a recognition-desired word recognition score indicating a similarity degree between the uttered word and each recognition-desired word is calculated. Also, a reception word recognition score indicating a similarity degree between the uttered word and each reception word is calculated. In cases where a particular recognition-desired word recognition score corresponding to a particular recognition-desired word is higher than the highest reception word recognition score, the utter word is recognized as the particular recognition-desired word, and an operation of an electric apparatus is controlled according to the particular recognition-desired word. In contrast, in cases where a particular reception word recognition score corresponding to a particular reception word is higher than the highest recognition-desired word recognition score, the utter word is recognized as the particular reception word and is rejected, so that the electric apparatus is not operated.
