In this paper we present a h ybrid statistical and rule-based segmentation system which takes into account phonetic variation of German. Input to the system is the orthographic representation and the speech signal of an utterance to be segmented. The output is the transcription (SAM-PA) with the highest overall likelihood and the corresponding segmen-tation… (More)
Our approach to the problem of evaluating segmentations and transcriptions of speech data is presented. We developed an automatic pattern-matching procedure that relates different manual or automatic segmentations to each other. The comparison of segmentations refers to the degree of identity concerning the chosen labels and of identity of segment… (More)
In this paper 1 two dierent models of pronunciation are presented: the rst model is based on a rule set compiled by an expert, while the second is statistically based, exploiting a survey about pronunciation variants occurring in training data. Both models generate pronunciation variants from the canonic forms of words. The two models are evaluated by… (More)
This paper presents results of a first study for a human-robot-interaction in which the robot Flobi autonomously plays the game 'pairs' against a human player. Integrated is a dialog system which can use different dynamic sentence structures for altering the verbal output during the interaction. The system is compared with a dialog system using static… (More)
Teaching Social Robotics is a requiring and challenging task due to the interdisciplinary of this research field. We think that it can not be taught in a solely theoretical manner. To help students to gain more interest in the topic and to foster their curiosity we restructured a paper club like lecture to create a bridge between a theoretical topic and… (More)
Social robots are designed to interact in a more human and intuitive manner. In this hands-on demo we present an emotional system which is capable to produce human like emotional expressions. Via touchscreen given input results in a realtime facial expression on a physical and a simulated robot head.
