Human conversational partners are able, at least to a certain extent, to detect the speaker’s or listener’s emotional state and may attempt to respond to it accordingly. When instead one of the interlocutors is a computer a number of questions arise, such as the following: To what extent are dialogue systems able to simulate such behaviors? Can we learn the mechanisms of emotional be- viors from observing and analyzing the behavior of human speakers? How can emotionsbeautomaticallyrecognizedfromauser’smimics,gesturesandspeech? What possibilities does a dialogue system have to express emotions itself? And, very importantly, would emotional system behavior be desirable at all? Given the state of ongoing research into incorporating emotions in dialogue systems we found it timely to organize a Tutorial and Research Workshop on A?ectiveDialogueSystems(ADS2004)atKlosterIrseein GermanyduringJune 14–16, 2004. After two successful ISCA Tutorial and Research Workshops on Multimodal Dialogue Systems at the same location in 1999 and 2002, we felt that a workshop focusing on the role of a?ect in dialogue would be a valuable continuation of the workshop series. Due to its interdisciplinary nature, the workshop attracted submissions from researchers with very di?erent backgrounds and from many di?erent research areas, working on, for example, dialogue processing, speech recognition, speech synthesis, embodied conversational agents, computer graphics, animation, user modelling, tutoring systems, cognitive systems, and human-computer inter- tion.

Download Handling Emotions in Human-Computer Dialogues Book in PDF, ePub and Kindle
In this book, a novel approach that combines speech-based emotion recognition with adaptive human-computer dialogue modeling is described. With the robust recognition of emotions from speech signals as their goal, the authors analyze the effectiveness of using a plain emotion recognizer, a speech-emotion recognizer combining speech and emotion recognition, and multiple speech-emotion recognizers at the same time. The semi-stochastic dialogue model employed relates user emotion management to the corresponding dialogue interaction history and allows the device to adapt itself to the context, including altering the stylistic realization of its speech. This comprehensive volume begins by introducing spoken language dialogue systems and providing an overview of human emotions, theories, categorization and emotional speech. It moves on to cover the adaptive semi-stochastic dialogue model and the basic concepts of speech-emotion recognition. Finally, the authors show how speech-emotion recognizers can be optimized, and how an adaptive dialogue manager can be implemented. The book, with its novel methods to perform robust speech-based emotion recognition at low complexity, will be of interest to a variety of readers involved in human-computer interaction.

Download Creating an Emotion Responsive Dialogue System Book in PDF, ePub and Kindle
The popularity of deep neural networks and vast amounts of readily available multi-domain textual data has seen the advent of various domain/task specific and domain agnostic dialogue systems. In our work, we present a general dialogue system that can provide a custom response based on the emotion or sentiment label selected. A dialogue system that can vary its response based on different affect labels can be very helpful for designing help-desk or social help assistant systems where the response has to follow a certain affective tone, such as positive, compassionate, etc. To address this task, we design a model that can generate coherent response utterances conditioned on a specified affect label (emotion or sentiment). We use a Sequence-to-Sequence model with an adversarial objective to remove affect from the learned representation of the input utterance, and generate the response based on this representation and the target affect label. Two models were evaluated: affect embedding and multi-decoder. We hypothesize that removal of the affect from the input utterance is helpful in generating a response conditioned on a different affect label. The models were evaluated on a large Twitter dialogue corpus. The results support our hypothesis.

Download Emotion-Oriented Systems Book in PDF, ePub and Kindle
Emotion pervades human life in general, and human communication in particular, and this sets information technology a challenge. Traditionally, IT has focused on allowing people to accomplish practical tasks efficiently, setting emotion to one side. That was acceptable when technology was a small part of life, but as technology and life become increasingly interwoven we can no longer ask people to suspend their emotional nature and habits when they interact with technology. The European Commission funded a series of related research projects on emotion and computing, culminating in the HUMAINE project which brought together leading academic researchers from the many related disciplines. This book grew out of that project, and its chapters are arranged according to its working areas: theories and models; signals to signs; data and databases; emotion in interaction; emotion in cognition and action; persuasion and communication; usability; and ethics and good practice. The fundamental aim of the book is to offer researchers an overview of the related areas, sufficient for them to do credible work on affective or emotion-oriented computing. The book serves as an academically sound introduction to the range of disciplines involved – technical, empirical and conceptual – and will be of value to researchers in the areas of artificial intelligence, psychology, cognition and user—machine interaction.

Download Towards Expressive Perception and Generation in Human-Computer Conversational Interaction Book in PDF, ePub and Kindle
The construction of a natural interactive human-computer interaction has become an integral component of intelligent system development, constituting a core subject within the field of human-computer interaction. Grounded in the utilization of human perception theories, this study proposes a robust method for speech emotion recognition and a model for inferring user emotional state changes, thereby achieving a hu-man-computer interaction experience characterized by both listening and articulating, and conveying sentiments effectively. Simultaneously, focusing on the audio-visual modalities within human-computer interaction, this research explores methods for con-structing interactive feedback in auditory and visual modalities within real hu-man-computer dialog scenarios. This aims to synchronize textual, verbal, and visual expressions in human-computer interaction, enhancing its naturalness, improving user experience, and augmenting satisfaction and pleasure during interaction. The research contributions are as follows: Introducing a method that robustly identifies user emotional states in real hu-man-computer speech dialogue scenarios through the utilization of local and global attention mechanisms. This method generates robust and distinguishable representa-tions of speech emotion, thereby enhancing the robustness and accuracy of speech emotion recognition systems in authentic dialogue scenarios.
