Space-Time Signals -- Optimum Linear Filtering -- Optimum Beamforming for Wideband Non-Stationary Signals -- A Practical Audio Acquisition System Using a Robust GSC (RGSC) -- Beamforming Combined with Multi-Channel Acoustic Echo Cancellation -- Efficient Real-time Realization of an Acoustic Human/Machine Front-End -- Summary and Conclusions -- A Estimation of Signal-to-Interference-plus-Noise Ratios (SINRs) Exploiting Non-Stationarity -- B Experimental Setups and Acoustic Environments -- C Notations.
With a continuously increasing desire for natural and comfortable human/machine interaction, the acoustic interface of any terminal for multimedia or telecommunication services is challenged to allow seamless and hands-free audio communication. Sound Capture for Human-Machine Interfaces introduces the practical aspects of microphone array signal processing and presents various combinations of beamforming and acoustic echo cancellation.
