Abstract

Speech processing is finally starting the transition to wider bandwidths. The benefits include increased intelligibility and comprehension and a more pleasing communication experience. High quality full-duplex Acoustic Echo Cancellation (AEC) is an integral component of a hands-free speakerphone communication system because it allows participants to converse in a natural manner (and without a headset!) as they would in person. Some high-end Telepresence systems already achieve life-like communication but are computationally demanding and prohibitively expensive. The challenge is to develop a robust Acoustic Echo Canceller (AEC) that processes full-band audio signals with low computational complexity and reasonable memory consumption for an affordable Telepresence experience.
