滑に行なうことができる。When a faucet user inputs voice to the voice input means 1, the voice is input to the voice input means 1 with the sound of running water such as tap water, which is a noise component, being included in the voice. At this time, the electrical signal of the voice input to the voice input means 1 is converted into a frequency domain by the frequency analysis means 2, and A
The /D converter 3 converts the analog signal into a digital signal, and the audio section analysis processing means 4 converts the audio pattern containing the running water sound component. However, in the speech pattern containing the running water sound component obtained by the speech section analysis processing means 4, the sound component of the running water is not uniform depending on the flow rate, which causes a decrease in the speech recognition rate. Therefore, in order to remove the running water sound component from the sound pattern containing the running water sound component obtained by the speech section analysis processing means 4, the noise energy calculation means 5 uses a sampled signal before the start of the sound in the A/D conversion section 3. The noise energy is calculated from the digital signal, and the electric signal of the running water sound inputted to the directional running water sound input means 6 installed near the faucet is converted into the frequency domain by the frequency analysis means 7, and the A/D Deflection part 8
Converts analog signals to digital signals. The running water level adjustment means 9 converts the level to a level that has the same energy as the energy calculated by the noise energy calculation means, and the running water sound analysis processing means 10 converts it to a level that has the same energy as the energy calculated by the noise energy calculation means. The running water sound component sampled in the interval is converted into a running water sound pattern. By subtracting the running water sound pattern obtained by the running water sound analysis processing means 10 from the sound pattern containing the running water sound component obtained from the sound section analysis processing means 4 by the running water sound component removal means 11, the running water sound component is obtained. is converted into a voice pattern that does not contain Therefore, a sound pattern not containing a running water sound component registered in advance in the sound standard pattern memory l2 and a sound pattern not including a running water sound component obtained by the running water sound component removal means 11 are compared. By determining the degree of similarity by the processing means 13, it is possible to eliminate the influence of the sound of running water, which is a noise component, and suppress a decrease in the speech recognition rate. The flow rate (a) is selected from the registration means 14, the current flow rate value is determined by the flow rate detection means 15, and the flow rate value selected from the flow rate value registration means 14 and the flow rate value determined by the flow rate detection means 15 are calculated as the flow rate. A preset flow rate value can be obtained instantaneously by making a comparison using the comparing means 16 and operating the valve 18 by applying an electric signal to the actuator 17 so that the comparison values match, thereby facilitating electronic flow control using voice commands. can be done.
