Amazon on Thursday expanded more functionality to its Amazon Tap speaker via an over-the-air update that adds the hands-free capability to summon the Alexa voice assistant.

Prior to the update, Tap users would need to press a button to activate Alexa -- the only speaker in the lineup to require to do so manually. Now, they can summon Alexa with commands from across the room.

The hands-free capability can be enabled through Settings in the updated Alexa app. Once enabled, the always-on microphone could have a faster drain on the Tap's battery.

Amazon said the update also adds Echo Spatial Perception (ESP) that "works in environments with multiple Alexa-enabled devices to ensure that the correct device responds, or does not respond, when the 'Alexa' wake word is detected."
