💡 How a Smart Speaker Works
A smart speaker is a loudspeaker and voice command device with an integrated virtual assistant (like Amazon Alexa, Google Assistant, or Apple Siri). It acts as a central hub for hands-free audio, information, and control of a connected home.
It goes far beyond a simple Bluetooth speaker by including Wi-Fi capabilities, microphones, and advanced Artificial Intelligence (AI) to understand and respond to spoken requests.
Audio Capture & Transmission: Once the wake word is detected, the speaker records the subsequent command and uses its Wi-Fi connection to send the audio clip to the provider's cloud service (Amazon, Google, Apple).
Wake Word Detection: The built-in microphones are always listening for a specific "wake word" (e.g., "Alexa" or "OK Google"). Until the wake word is detected, the device only processes a small audio buffer on the device itself.
