Towards Situation-Adaptive In-Vehicle Voice Output
Daniela Stier, Katherine Munro, Ulrich Heid, Wolfgang Minker · 2020
Human-machine interaction is increasingly speech-based, with a trend away from the earlier command-based style towards natural, intuitive dialogues based on the human model. A prerequisite is the ability of a Spoken Dialogue System to flexibly react according to individual requirements, e.g., by means of adaptive voice output. The necessity to maximize the efficiency of language interaction through alignment at all linguistic levels becomes particularly relevant in dual-task situations. Here speech represents a secondary task in parallel to a prioritized primary task, such as driving a car. In addition to the individual requirements of a user, the demands of the interaction context need to be considered. For this purpose, it is beneficial to examine the particular characteristics of user language during the performance of a primary task.
