METHOD AND APPARATUS FOR USE IN INTERACTIVE DIALOGUE ABSTRACT A dialogue controller (15) and a speech recogniser (11) are provided for obtaining classified information from utterances spoken by a user in a dialogue. Templates to enable the recogniser to recognise utterances are grouped in logical templates comprising templates of a given utterance and utterances which are equivalent from the point of view of the dialogue controller for a particular part of the dialogue. A logical template CONFIRM may include templates for "Yes", spoken by different speakers and also templates for "Yeah", "Confirm" and other synonyms. The dialogue controller does not need to know which template has been matched: the logical template COFIRM is identified and the appropriate classified information is sent to the dialogue controller. In a telephone information service, the apparatus includes a speech synthesiser (13), a telephone monitor interface (17) and a data store.
