The Durham telephone enquiry system
The Durham telephone enquiry system is a speaker/gender independent telephone enquiry service which operates in real-time. The system has been successfully applied to English and Italian telephone databases of up to 100,000 entries.
The mechanism by which the telephone database is searched is a key feature of the enquiry system and is based upon a management-of-uncertainty methodology. The practical result of which is that there is no expectation that the user's utterances will always be correctly interpreted by the speech recognition stage. This paper contains a description of the components of the system and how they are integrated. Issues which had to be addressed in ensuring that the system operates in real-time on ‘live’ input are also discussed.
