Spontaneous-Speech Dialogue System In Limited Domains

 

 


Project Information


Overview


    Over the last few years, the research teams involved in this coordinated project have acquired experience in continuous speech recognition and synthesis and in natural language processing. In this project, they will apply the acquired knowledge to the development of an oral human-machine interface, by way of dialogue, for a semantically limited task: queries into a database with information regarding railway ticket reservation. The project includes:

  1. the acquisition of a corpus so as to study the dialogue in the task.
  2. a study on spontaneous speech and its modeling.
  3. the development of robust speech signal modeling techniques, to cope with variations due to speaker, background and channel effects.
  4. the study and development of the dialogue system in the semantically restricted environment of the task, including the speech recognition and understanding module and the system that will generate an oral answer.
  5. the development of a prototype of the dialogue system for the given task over the telephone network.

    At the end of this project, the acquired knowledge and expertise on oral interfaces based on dialogue will allow the development of services unavailable today; for instance, accessing information or help, carrying out transactions over the telephone, etc. Alternatively, the enhanced interfaces may improve current services.

    This project is supported by CICYT (Comisión Interministerial de Ciencia y Tecnologia) of Spanish Government under grant TIC98-0423-C06.

    The project started on October 1998 and will end by September 2001.
