Infos

Before designing a speech application system, three key questions have to be answered: who will use it, why and how often? This book focuses on these high-level questions and gives a criteria of when and how to design speech systems. After an introduction, the state-of-the-art in modern voice user interfaces is displayed. The book goes on to evolve criteria for designing and evaluating successful voice user interfaces. Trends in this fast growing area are also presented.
