SIMULATION OF HUMAN-MACHINE DIALOGUES

September 1999
The field of spoken dialogue systems has developed rapidly in recent years. However, optimisation, evaluation and rapid development of systems remain problematic. In this research, a method was developed to produce probabilistic simulations of mixed initiative dialogue with recognition and understanding errors. Both user behaviour and system errors are modelled using a data-driven approach, and the quality of the simulations are evaluated by comparing them to real human-machine dialogues.
The simulation system can be used to perform rapid evaluations of prototype systems, thus aiding the development process. It is also envisaged that it will be used as a tool for automation of dialogue design.
If you have difficulty viewing files that end '.gz'
,
which are gzip compressed, then you may be able to find
tools to uncompress them at the gzip
web site.
If you have difficulty viewing files that are in PostScript, (ending
'.ps'
or '.ps.gz'
), then you may be able to
find tools to view them at
the gsview
web site.
We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
