Imagine walking into your home, saying a few words, and instantly turning on the lights, adjusting the thermostat, and starting your favorite playlist—all without lifting a finger. This isn’t science fiction; it’s the power of voice assistants like Amazon Echo and Google Home.
#1
Wake Word Detection: The device listens for a specific wake word, such as “Alexa” or “Hey Google.”
Command Processing: Once activated, it records your voice command and sends it to a cloud server for analysis.
Response Execution: The server processes the command and sends instructions back to the device or connected smart gadgets.
For example:
If you say, “Alexa, turn off the lights,” the Echo device communicates with your smart light bulb via Wi-Fi or Bluetooth to execute the command.
If you ask, “Hey Google, what’s the weather today?” the Google Home device retrieves the information from online sources and delivers it in real-time.
