The Amazon Echo First Gen
The Amazon Echo first generation has seven microphones and beamforming technology so it can hear you from across the room—even while music is playing. Echo is also an expertly tuned speaker that can fill any room with 360° immersive sound. When you want to use the Amazon Echo first generation, just say the wake word “Alexa” and Echo responds instantly. If you have more than one Echo or Echo Dot, Alexa responds intelligently from the Echo you’re closest to with ESP (Echo Spatial Perception).
