摘要： 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 (80) from a first database of digitally recorded spoken utterances (82). The previously recorded utterances are digitally processed to create a second database (84) of modified utterances and then the first and second databases are combined (86) to form an expanded database from which recognition vocabulary tables may be generated (88).
