Abstract:
A system, article, and method of acoustic dereverberation factoring the actual non-ideal acoustic environment.

Claim (Index 14):
A method of automatic speech or speaker recognition, comprising:\n receiving, by at least one processor, multiple audio signals comprising audio signals of human speech contaminated by reverberations formed by objects in or forming an actual acoustic environment, wherein the reverberations comprise reverberation components and residual reverberation components; pre-processing comprising dereverberation of at least a sub-band of the audio signals and comprising:\n receiving, by at least one processor, multiple audio signals comprising dry audio signals divided into time-frames and contaminated by reverberations formed by objects in or forming the actual acoustic environment wherein the reverberations comprise reverberation components and residual reverberation components; \n de-correlating, by at least one processor, past time-frames from a current time-frame to generate multichannel estimates of residual reverberations, \n performing, by at least one processor, post-filtering by generating an interference matrix using the multichannel estimates of residual reverberations, and \n reducing, by at least one processor, the residual reverberation components in the output signal comprising applying the interference matrix; and \n analyzing the pre-processed audio data to recognize words in the speech or match the acoustic signal of the audio data to recognized voice signals.
