SYSTEM AND METHOD FOR GENERATING AN IMPROVED VOICE ASSIST ALGORITHM SIGNAL INPUT

摘要

An improved system for generating a Voice Assistant engine input signal in a Voice-Controlled loudspeaker 404 and a method for generating the Voice Assistant engine input signal includes (a) obtaining a return audio reference signal for a specific loudspeaker unit, (b) sensing or calculating a desired transfer function Η(ω,t) for the unit, (c) modifying the return audio reference signal with the desired transfer function Η(ω,t) to provide a corrected return audio reference or cancellation signal, and (d) applying the filtered corrected return audio reference or cancellation signal to a voice signal to generate an enhanced and more intelligible VA engine input signal.
