Visualizing Pragmatic Features in Spoken Interaction: Intentions, Behavior and Evaluation
Interactive and semi-automatic processing facilitates the correct perception and evaluation of pragmatic features in spoken interaction, especially in discussions and interactions beyond a defined agenda and specified protocol, such as interviews and live conversations in Skype or in the Media. Pragmatic features, in particular, indicators of a Speaker’s attitude-behavior and intentions can be visualized in distinctive annotations in generated messages and generated graphic representations. Pragmatic information can be extracted from semantic-linguistic information or a combination of linguistic information with paralinguistic features. The visualization of pragmatic features enables a user-independent evaluation of information content, Speaker behavior and the success or failure of a spoken interaction, including a discussion or interview. This possibility is of particular importance in spoken interaction with non-native speakers of a natural language and when an international public is concerned.
