Abstract
The present invention comprises a method for reducing the database requirements necessary for use in speaker independent recognition systems. The method involves digital processing of a plurality of recorded utterances from a first database of digitally recorded spoken utterances. The previously recorded utterances are digitally processed to create a second database of modified utterances and then the first and second databases are combined to form an expanded database from which recognition vocabulary tables may be generated.
