Amazon Tap, US$129(?):
Quote:
Alexa, aka the Amazon Echo, is coming to two new members of the product line. The Amazon Tap is a portable version of the Echo to allow taking Alexa everywhere. The Echo Dot is a small device designed to augment existing Echo installations.
The Amazon Tap looks like a shorter Echo and has a battery (nine hours music playback, and three weeks standby) allowing it to go mobile. It's reminiscent of portable speakers from other vendors, but with Echo capabilities. The Tap has a microphone button that is pressed to speak commands.

Amazon Echo Dot, $89:
Quote:
Joining the Tap is the Echo Dot, a device that looks like a hockey puck. Unlike the original Echo and the new Tap, the Dot only has a small speaker to handle functions like sounding alarms.
The Dot is designed to install in homes that have an Amazon Echo. It's essentially an extension of the Echo to put in rooms outside the Echo's reach. It can eliminate the need to have multiple Echos in rooms to control smart home appliances. Put Dots in each room where control is needed and connect the Dots to the network.
The Echo Dot has the far-field audio technology used in the Echo along with a ring of lights on top of the device to indicate what is happening. The small speaker allows the Dot to work well as an alarm clock that operates by voice.

The Dot can only be purchased via Alexa itself.
It'll be interesting to see if multiple Dots will allow multiple audiobook and/or ebook TTS sessions simultaneously.
