Abstract
A voice interaction architecture has a hands-free, electronic voice controlled assistant that permits users to verbally request information from cloud services. The voice controlled assistant may be positioned in a room to receive voice commands from the user. The voice controlled assistant may also pick up background sources of speech, music, or other noise, such as from a television or stereo system, which may adversely impact the user's intended vocal input to the assistant. The assistant transmits the aggregated audio data (user command and background noise) over a network to the cloud services, which implements noise cancellation functionality to remove the background noise while isolating and preserving the user's command. Once isolated, the cloud serves can process and interpret the user input to perform some function, and return the response over the network to the voice controlled assistant for audible output to the user.
