What is Sapi?

Sapi is an interface of the Windows operating system. This means that an application first talks to the interface and then the interface talks to the sapi synthesiser.

However in a reading situation such delay are not usually detectable.

At installation the details of the users computer are taken and a license transferred from the floppy to the machine hard drive. Each user has two licenses, one to use and one as a back up. Some users use both licenses, one for home and the other at work, however it is not allowed to use both licenses at the same time as the user agrees at installation. Recovering a license to transfer to another computer is very easy. Re-install the CD and the user is offered the automatic choice to remove the software and recover the license.
