In this paper the possible sources of inaccuracies of a spoken dialog system are discussed, and the approaches to address each of them are surveyed.

Spoken dialog managers have benefited from stochastic planners such as MDPs. However, so far, MDPs do not handle well noisy and ambiguous utterances from the user. We address this problem by inverting the notion of dialog state; the state represents the user's intentions, rather than

The Ritel project aims at integrating spoken language dialog and open-domain information retrieval to allow a human to ask gen-eral questions (e.g. Who is currently presiding the French Senate?) and refine her search interactively. This project is at the junction of several distinct research

Interactive spoken dialog systems extend the range of automated telecommunication services beyond simple limited-choice form-filling applications to goal-directed tasks covering richer, more complex domains. Creating effective and efficient dialog systems requires not only accurate and robust

Abstract—The importance of automatically recognizing emotions from human speech has grown with the increasing role of spoken language interfaces in human-computer interaction applications. This paper explores the detection of domain-specific emotions using language and discourse information

Engineers have long sought to design systems that understand and act upon spoken language. Extracting meaning from natural, unconstrained speech over the telephone is technically challenging, and quantifying semantic content is crucial for engineering and evaluating such systems. Traditional menu

In this paper we give an overview of a Slovenian spoken dialog system. Such a system has to be able to handle spontaneous speech, and to provide the user with correct information. The Slovenian information system is used for air flight information retrieval. The system has to answer questions about

A major hindrance to rendering spoken dialog systems capable of ongoing, continuous listening without requiring a push-totalk device is the problem of distinguishing speech which is intended for the system from that which is overheard. We present a decision-theoretic approach to this problem
