Opis

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.

Recenzje

From the reviews:

"This is a research book, a monograph, devoted to an actual problem: the design of the acoustic front-end to provide a seamless and hands-free communication in the frame of the human / machine interaction. ... the theory is developed at an adequate mathematical level together with numerous experiments enforcing the conceptual frame. ... The book represents an excellent 'instrument de travail' for specialists in statistical and adaptive signal processing." (D. Stanomir, Mathematical Reviews, Issue 2006 e)
