JAWS 5.1 through 6.2 is required.
You can also install CakeTalking under JAWS 7.0 and
although many customers have had success with it,
we do not officially support it.
Unless you have already purchased Sibelius Speaking or intend to do so,
do not download and install the installation program for Sibelius Speaking.
Sibelius Speaking does not yet have a demo mode.
Without proper authorization,
Sibelius Speaking will report that you do not have an authorized copy of
Sibelius Speaking and will close Sibelius. You will be unable to use
Sibelius with JAWS until you uninstall Sibelius Speaking.
