Abstract (en)

[origin: WO2019136460A1] A system (400) and method for incorporating Voice-Controlled ("VC") or smart speaker system features into a separate high-performance host loudspeaker system (604) includes a "Smart Puck" VC module (404) programmed to incorporate VC functionality into the separate host loudspeaker system (604). The Smart Puck VC module (404) includes a microphone array (424) and senses noise stimuli emitted by the separate host loudspeaker system (604) in a user's listening space which is used to derive a complex transfer function (TF) between the host loudspeaker system and the microphone array, and the captured TF is utilized to improve the VC speaker system's sound in the listening space.
