Patent number: 8194852Abstract: An echo reduction system includes a signal analysis filter that converts an input into sub-band signals. A signal down-sampling circuit down-samples the sub-band signals at a first down-sampling rate. An echo analysis filter converts a loudspeaker signal into echo sub-band signal that are further processed by an echo down-sampling circuit. The circuit down-samples the echo sub-band signals at a second down-sampling rate to generate down-sampled echo sub-band signals. An echo compensation filter folds the down-sampled echo sub-band signals with an estimated impulse response of a loudspeaker-room-input system. A second echo down-sampling circuit down-samples the folded down-sampled echo sub-band signals at a third down-sampling rate to generate estimated echo sub-band signals. The first down-sampling rate is equal to the product of the second and third down-sampling rates.Type: GrantFiled: December 13, 2007Date of Patent: June 5, 2012Assignee: Nuance Communications, Inc.Inventors: Markus Buck, Tim Haulick, Martin Rössler, Gerhard Uwe Schmidt, Walter Schnug

Patent number: 8130969Abstract: An echo compensation system may remove undesirable audio signals. The echo compensation system may utilize adaptive filters to remove echoes and undesirable signals received by a microphone. The echo compensation system may inhibit adaptation of an adaptive filter when left and right channel audio signals are highly correlated. In a two-channel system, inhibiting adaptation of one of two adaptive filters may reduce computational power requirements, while still removing undesirable signals. In a four-channel system, inhibiting adaptation of all but one of the four adaptive filters may reduce computational power requirements by a greater percentage.Type: GrantFiled: April 16, 2007Date of Patent: March 6, 2012Assignee: Nuance Communications, Inc.Inventors: Markus Buck, Tim Haulick, Martin Roessler, Gerhard Uwe Schmidt

Patent number: 8111840Abstract: A system for reducing an echo and/or a residual echo in a microphone output signal includes an echo compensation filter configured to receive audio input signals and generate an estimated echo signal. A speech activity detector is configured to detect speech of a local speaker, and a combining circuit is configured to generate an echo compensated signal by subtracting the estimated echo signal from the microphone output signal. A residual echo reduction circuit is configured to suppress the residual echo in the echo compensated signal based on the detected speech activity, and output an echo suppressed output signal. The echo reduction system may reduce local background noise and residual echoes in a microphone output signal so that local speech may be transmitted free from undesirable signals.Type: GrantFiled: April 18, 2007Date of Patent: February 7, 2012Assignee: Nuance Communications, Inc.Inventors: Tim Haulick, Gerhard Uwe Schmidt, Martin Roessler
