Amazon’s Alexa assistant has taken its place in some living rooms as a center point for music, internet functions, and smart home decides. On Thursday the company announced two more devices expanding Alexa’s abilities, Amazon Tap and Echo Dot.

Both are built using aspects of Amazon Echo, the smart cylinder that came out in 2014 and supported Alexa. The new speaker aspect is the Echo Dot, which can play music through its own speakers or connect to another audio system. It also serves as Alexa’s general audio interface, through which the assistant can answer questions or play alarms.

Meanwhile, the Tap is about half the size of the Echo, at 6.25 inches. It doesn’t require being plugged in, and can pull music from streaming sites or speak to Alexa when connected to wi-fi. It does require a touch (thus the “tap”) in order to activate it, which serves to conserve the battery when the device is not being used.

The two devices are cheaper than the $180 on its own, with the Tap selling for $130 and the Echo Dot at $90. Either one could be utilized in addition to the existing Echo if a customer wants to expand the range of places from which they can call Alexa, but at the moment the Dot is only available for purchase by Amazon Subscribers who already own an Echo or the Amazon Fire TV set-top box. Both items are available for pre-order now, with shipments expected in March.

With the Echo Dot and Tap, Amazon can expand its infrastructure of listening assistants. Its most consumer-friendly use might be as a speaker system that can pump most of the major streaming services into any room of a house, but it could also deepen a smart home ecosystem, if the user has enough connected devices that they want a central hub be able to inquire into all of them.
