Abstract
The invention relates to a method and apparatus for automatically generating probability tables (histograms) for a speech recognition dictionary for use in a speech recognition system from a listing containing call records. The method comprises the step of generating histograms representing the probabilities of localities being requested based on the calling pattern collected on the field by either a human operator or via an automatic process during calls. The method is particularly useful for generating an a priori advisor for a speech recognition dictionary used in an automated system for locality recognition.
