Sound Capture for Human / Machine Interfaces

Autor Wolfgang Herbordt
en Limba Engleză Paperback – 22 mar 2005
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.

Recenzii

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)
