Taught by the author of Practical Speech User Interface Design, this session covers the current leading practices in speech user interface design for interactive voice response applications. Drawing from psychology, human-computer interaction, linguistics, and communication theory, this course provides a comprehensive yet concise survey of practical speech user interface (SUI) design, including practice-based and research-based guidance on how to design effective, efficient, and pleasant speech applications. The techniques for designing usable SUIs are not obvious, and to be effective, must be informed by a combination of critically interpreted scientific research and leading design practices.
