Abstract: A system and method for receiving sound from a teleconference host at a teleconference phone is disclosed. The method comprises identifying a person to act as the teleconference host. A location of the identified teleconference host relative to the teleconference phone is determined. A plurality of microphones on the conference phone are configured as a beamforming receiver to receive an audio signal from the location of the teleconference host. Selected microphones from the plurality of microphones are biased to receive sound from the direction of the teleconference host relative to sound received from other directions.

Abstract: The enhancements provided herein are designed to allow an acoustic echo suppressor algorithm to operate with significant echo path delay between an audio block Rin and audio block Sin. In one illustration, a single reference sample or envelope value can be taken from the received audio block Rin. Through an algorithm, echo signals can be suppressed and/or masked from audio block Sin by delaying the previously captured reference sample and aligning the delayed reference sample with multiple samples of the audio block Sin. Instead of each individual reference sample being matched with an individual sample of the audio block Sin, a single captured and delayed reference sample or envelope value can be matched with multiple samples of audio block Sin. The algorithm presented improves voice quality on a telephone call while reducing buffer requirements.
