PROBLEM TO BE SOLVED: To provide a voice recognition device in which the amount of arithmetical operation required for recognition processes can be reduced and the required storage capacity can be also reduced. SOLUTION: The device is characterized in that it is provided with an input means which inputs voice, a smoothing means which smooths the shapes of the voice waveforms being represented on the time-amplitude coordinate axes of the inputted voice, an island number detection means which recognizes the lumps of voice stimulating portions in the smoothed voice waveforms as islands and detects the number of the islands, a storage means storing a voice database in which recognition object words with which the number of islands is associated as one of a plurality of parameters and a fixed processing means which conducts a fixed processing for the words of the inputted voice and the recognition object words using remaining parameters only for the recognition object words that have a same number of islands as the detected number of islands of the input voice.
