What is Sapi?
Sapi is a Windows interface which allows applications to output information in spoken form. Applications have to follow the rules of passing information to the Sapi speech engine in accordance to the specification defined by Microsoft. As the Sapi engine acts purely as voicing audio output is the requirement that any application that uses Sapi must use the Sapi interface correctly.

What is the difference between Sapi4 and Sapi5?
Sapi5 is designed for Windows XP operating systems, whereas Sapi4 is suitable for other Windows operating systems. Whilst Sapi5 can be made to work on non XP, Portset are not providing support for Sapi5 on non XP systems.

Why is Sapi slow sometimes?
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. If the synthesiser has to respond to the application then the return route takes the reverse procedure. This introduces delays which can become apparent on simple actions like keystrokes. However in a reading situation such delay are not usually detectable.

Which applications will work with KeySpeak Sapi Voice?

Which Screen Readers work with Sapi?
From tests conducted by Portset during 2002 the three major screen readers, namely, Window Eyes, Hal and Jaws were able to access KeySpeak Sapi Voice Sapi4. Only Hal could access in addition the KeySpeak Sapi Voice SAPI5 synthesiser. This is a moving situation as screen reader manufacturers add additions and improvements to their products. Whilst both Window Eyes and Hal can automatically detect sapi compliant synthesisers at time of this publication Jaws needs editing of the JFW.INI file manually by the user. Get the Jaws ini file example and notes.

As a Jaws user, what do I have to do?
The Jaws screen reader requires user action to allow sapi voices. Unlike other screen readers, Jaws Version 4.5 does not automatically identify sapi voices. The user must manually modify the JFW.INI file. Get the Jaws information in RTF format

How does the license system work?
The KeySpeak Sapi Voice is provided on a CD together with a floppy disk that contains the license for user use. The system is software protected to ensure that illegal coping is prevented.

To do this it protects its products. A KeySpeak Sapi Voice User will be able to install in a very simple way, You can even chose the drive and folder location. 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.
