Language-specific as well as culture-specific factors are observed to play a decisive role in User Specifications for spoken Human--Computer Interaction (HCI) systems. This book determines and defines a finite set of re-usable, transferable and language independent specifications for prosodic modelling used as general parameters for the Speech Component in Human--Computer Interaction (HCI) Systems and, specifically, in Service-Oriented Dialog Systems, constituting an application field of HCI, usually directed to the General Public as a user group. Factors related to special applications such as emotion recognition, and/or special user groups, such as children or handicapped users, are not included in the present analysis.
