Voice control electric appliance system

Abstract

The invention discloses a voice control system that includes host computer and voice controller. An audio frequency wireless emitting circuit is installed in the host computer. In the voice controller, a receiving circuit is installed in. the voice control signal and voice from host computer speaker would be received by microphone. After canceling of the two channel signals, the left voice control signal would take voice recognition. The recognition control signal would control the host computer by wireless mode. The invention could be used in vocalization host computer, disvocalization host computer, or a vocalization host computer containing one or several disvocalization host computers. Under the circumstance of taking voice controlling, the control is promptness, and recognition rate is high.

Description

Technical field [0001] The present invention relates to an electrical appliance system, in particular to a system that can control electrical appliances through voice. Background technique [0002] At present, electrical systems with voice control functions have begun to appear. Because of the convenient control and operation, they have broad market prospects. The general technical solution is to use a microphone to pick up the voice control signal, and then amplify it through an amplifier, and then process the amplified signal with a voice recognition module, and finally generate a remote control command to control the host. The existing technical solutions can reach the use state for one or more hosts (such as air conditioners, refrigerators, etc.) that do not produce sound. However, in actual use environments, there are often hosts that produce sound, so they are difficult to promote and apply. Because if the controlled host makes a sound or one of the multiple hosts makes a s...

AI Technical Summary

Problems solved by technology

Existing technical solutions can be used for one or more hosts that do not make sound (such as air conditioners, refrigerators, etc.), but in actual use environments, there are often hosts that make sounds, so they are difficult to popularize and apply

Because if the controlled host makes a sound or one of the multiple hosts makes a sound, the voice control signal and the sound signal from the host will be mixed, and the probability of the voice recognition module will be greatly reduced, resulting in control failure or malfunction.
