PROBLEM TO BE SOLVED: To interactively given an alarm to a speaker so as to talke at a proper voice level when an input voice level is not within a proper range without necessitating additional circuits. SOLUTION: In a speech recognition system responding to a voice while recgnizing a speech, an input voice level judging part 10 judging levels of input voice data is provided so as to become the preceding stage of a speech recognizing part 20 in a CPU in which the part 20 is mounted and when the level of the input voice data is judged to be out of a reference range, this system is made to interactively perform the alarm of the result of the judgment and in the case the level is judged to be within the reference range and when the system is in the registration mode of the input voice data, the registring of the input voice data is performed by the recognizing part 20 and when the system is in the recognition mode of the input voice data, the recognizing of the speech is performed by the recognizing part 20.
