Title: A Theory of Error Recognition and Repair

Errors made by automatic speech recognisers are ubiquitous; often over one 
in ten hypotheses are wrong.  This confounds the management of dialogues 
introducing wrong facts or instructions, increasing the chance of subsequent 
errors and creating repetitive re-prompting.  Recognition is a 
classification task and errors are likely to continue.  We must, therefore, 
develop a theory that will allow a system to realize when it is mishearing 
and to take action to repair the mishearing.

Until this problem is solved the semantic and syntactic analysis of 
utterances will often fail and users will continue to face frustration and 
task failure in an unacceptable number of cases.
