A Voice Control Relay is an electronic device that allows users to control electrical equipment such as lights, fans, or home appliances through voice recognition systems. It serves as a bridge between a voice recognition module (like Amazon Alexa, Google Assistant, or Apple Siri) and an electrical relay, which switches devices on or off. With the advancement of artificial intelligence (AI) and smart home technology, voice control relays have become an increasingly popular component in smart homes, enabling effortless and hands-free control of various household gadgets.
