摘要

A method of reducing the perplexity of a speech recognition vocabulary anddynamically selecting speech recognition acoustic model sets used in asimulated telephone operator apparatus. The directory of users of thetelephone network is subdivided into subsets wherein each subset contains thenames of users within a certain location or exchange. A speech recognitionvocabulary database is compiled for each subset and the appropriate databaseis loaded into the speech recognition apparatus in response to a requestedcall to the location covered by the subset. Furthermore, a site-specificacoustic model set is dynamically loaded according to the location of acalling party. An apparatus for carrying out the method is also discussed.
