Gestión de la identidad de locutor y perfiles de usuario en un sistema de diálogo

In this paper we present an approach to capture user preferences during their interactions with a spoken dialogue system (SDS) and to exploit these preferences into the dialogue manager module. We use the output of an unsupervised speaker identification module and a natural language understanding module to adapt the behaviour of the SDS to each particular user by developing a statistic analysis...

Verificación de tema en sistemas de diálogo mediante la aplicación de un test de hipótesis bayesiano

One of the most difficult aspects of any dialogue system is the identification of user intention and recognition errors. In this paper, we present a novel approach to the task of deciding what the user has said and what she wants to do next. We use statistic classifiers driven by confidence measures which are generated in parallel by several topic-adapted speech recognizers. This approach has s...

Uso de información contextual en la interfaz de entrada de un sistema de diálogo

This paper proposes a new technique that aims to enhance the performance of the input interface of spoken dialogue systems by means of combining the advantages of the prompt-dependent and prompt-independent grammars used by these systems. The technique proposes creating a two-level speech recogniser since it contains two modules. The first one is a continuous-speech standard recogniser that rec...

Medidas de confianza en sistemas de diálogo

This paper investigates improved confidence assessment for spoken dialogue systems at three levels: word, concept and utterance levels. The confidence scores are used to detect word-level speech recognition errors, incorrect concepts and out of domain or miss-understood utterances in the CU Communicator system. New measures from the speech understanding component are proposed for confidence ann...
