Data acquisition and error correcting speech recognition system

摘要

The present invention provides a data acquisition and error correcting speech recognition system especially adapted for use in mobile telecommunications switching offices. The system comprises speech recognized dialing information with historical user calling information and attempts to determine whether the dialing information has been misspoken or misrecognized. If a mistake appears likely, the system suggests corrected dialing information to the user. The system also maintains data on the likelihood of various components of dialing information being misrecognized and updates this information with each call. The historical calling information indicates the user's propensity to call within particular area codes and office codes, to call particular phone numbers, and to call at particular times of day.
