Amazon Echo
• Hands-free speaker.
• Echo connects to the Alexa Voice Service and then
user can ask query.

technology so it can hear you from across the
room.
• Omni-directional sound.
• When you want to use Echo, just say the wake
word "Alexa" and Echo responds instantly.
Fig.1 Amazon Echo [4]
Echo Dot and Tap
• Has a tiny speaker, otherwise same as
Echo – so called Echo Dot.
• Typically you'll hook Dot up to your
own audio setup (via out jack
or Bluetooth), so you can use Alexa with
your existing speakers.
• The tiny speaker won't output much
audio - it's only for Alexa voice
feedback (which, again, requires Wi-Fi).
• Portable Bluetooth and Wi-Fi enabled
speaker.
• Unlike Echo, Tap is wireless & must be
set into the included cradle in order to
charge.
• The Tap isn't an always-on, so you can't
say "Alexa" to wake it and instead need
to press the microphone button on the
front.
