A smart speaker is a voice-activated device that uses artificial intelligence and internet connectivity to perform tasks, answer questions, and control smart home devices. Common examples include Amazon Echo and Google Home. These devices use built-in microphones to listen for voice commands, process them using cloud-based services, and respond with information, music, or actions like adjusting lights. From a cybersecurity perspective, smart speakers can pose privacy risks, as they continuously listen for activation words and may inadvertently record conversations. Ensuring strong security settings, regular software updates, and understanding data privacy policies are important to minimize potential threats associated with smart speakers.
