PURPOSE:To smoothly control flow rate by extracting from the composite pattern of voice inputted to a voice input means with running water sound the pattern of running water sound inputted to a running water sound input means when the running water sound is inputted to a voice input means. CONSTITUTION:When voice is inputted to a voice input means 1 with running water sound included in the voice, a voice signal is converted into a voice pattern including a running water sound component by a voice area analysing and processing means 4. Noise energy is calculated by a noise energy calculating means 4 and running water sound inputted to a running water sound input means 6 provided neer a faucet is converted by a running water level adjusting means 9 to a level where its energy equals to noise energy and the running water sound is converted into a running water sound pattern by a running water analysing and processing means 10, and the running water sound pattern is extracted from the voice pattern of the voice area analysing and processing means 4 by a running water sound component extracting means 11 and is converted to a voice pattern that does not include the running water sound component. Deterioration of the rate of voice recognition is thus restrained and flow rate control is smoothly carried out by voice commands.
