Several changes have been implemented that differentiate
this version of the Numbers Corpus from version 1.0. These
changes include the following:

* Speech files in the /speech directory have been 
  converted from NIST format to RIFF format.

* The directory structure has been modified so that 
  it is more logical and accessible.

  accurately reflects the corpus contents.

These and other changes have been made to make the corpus
more useful to the end-user.
