A Voice Control Relay is a device that integrates a traditional relay with voice recognition technology. A relay, in its simplest form, is an electrical switch that controls the flow of electricity in a circuit. By using a voice control relay, users can turn appliances on and off, adjust settings, and interact with their devices through voice commands rather than manually pressing buttons or using remote controls.

    The voice control relay typically consists of two main components： the relay module and the voice recognition system. The relay module is responsible for physically switching the electrical circuit, while the voice recognition system (often built into smart speakers or other devices like smartphones) processes the voice commands. When a user speaks a command, the voice recognition system interprets it, and if it matches a predefined command, the system sends a signal to the relay to activate or deactivate the connected appliance.
