A **smart speaker** is a voice-activated device that lets you play music, control smart home gadgets, set reminders, and ask questions—just by speaking. At its core, each smart speaker has a built-in **voice assistant** such as Alexa, Google Assistant, or Siri. These assistants help you manage your home by turning on lights, adjusting thermostats, locking doors, or playing audio.

Choosing compatible smart bulbs for your voice assistant is the key to hands-free lighting in a smart home. When a smart bulb actually works with voice assistants like Google Assistant or Alexa, you unlock true convenience—turning lights on, changing colors, or setting scenes just by speaking.
